How can I get this right? To help us help you, could you please prepare a repr oducible ex ample reprex illustrating your issue? Please have a look at this guide, to see how to create one:.

I hope this is enough, if not, please let me know. Really thank you for your help in advance. Have you read the link I gave you? I indeed read the link, but I did not completely understand what I had to do. I am just a beginner in Rstudio But I tried what you said I had to do and this is the result:. Created on by the reprex package v0. Yes, that was better, I have turned your data into a proper reprex to help you with that part, could you please elaborate a little more on what do you mean with "gives a messed up graph"?

I see now that the piece of code I used for making the bar is not copied correctly.

This is because there is 35 and 39,5 between 2,5 and 6,7. I would like to know how to make a graph that looks like the image I shared before.

Idk how but it changed all of the sudden?!? Ok, I think I know what is going on here, the previous image changed because I edited your post to make it a proper reprex, the difference is that in the example I made, the decimal mark is a dot and in yours is a comma and R is treating them as a categorical variable i.

I copied the code you edited in that post in my script and ran it, and it worked! This is the graph I was trying to make. Thank you so much for your help! Just for completeness this would be the solution converting Percentage column from text to numeric. This topic was automatically closed 21 days after the last reply.

Y-axis scale in Rstudio tidyverse. Hi, welcome! Thank you for your help!You can report issue about the content on this page here Want to share your content on R-bloggers? A colleague asked me for how one can change axis attributes in a basic plot. Plotting anything in R is really, really easy.

R Tutorial - Customizing Your Plots In R

It is enough typing plot x, y. In general, plot functions are nicely pre-cooked, so hardly one needs to change anything. Actually, we can change everything in the basic chart. To see how, just take a time yourself and type:? You will see how wealthy are the resources available. In the plot below, I plotted 6 scatterplots in only one object specially to show the chart manipulation.

In the first scatterplot: top-left-hand I show the result of a default plot. In the middle plot of the same row, there is a version without the two axes.

The third plot, in the top-right-hand, I added the x-axis just as it is. That is, without any manipulation of the numerical scale. In the fouth plot at bottom-left-hand, I added the y-axis to the plot, but still without manipulation. In the last plot, I also manipulated the scale of the x-axis to range from 0 to 3 by. The syntax of this example is shown bellow the chart. Want to share your content on R-bloggers?

Often we think of customized axes and labels in R plot, may be even inserting text. This is an effort to aggregate some of the things we look for every now and then.

Now waht we see here is the default plot generated by R. The symbols are by default chosen as circles, color is by default black, and the axes ranges and labels are chosen by default. We see the axis tick marks are all parallel to the respective axes.

Often we want to make it custimized like. A default plot Here some random numbers were generated to make a plot. First let us see what we get as default. Often we want to make it custimized like, Make the symbols other than circles Want different axis range Want different color Want all tick labels hozizontal Want to reduce the sapce between axis and label… and so on.

Let us try to do these customizations. We will only work on the base R graphics. Change Symbols and colors This is very simple task and done by passing pch and col arguments.By Andrie de Vries, Joris Meys. You can find all the documentation for changing the look and feel of base graphics in the Help page?

This function allows you to set or query the graphical parameters or options. Notice that par takes an extensive list of arguments. Here are a few of the most commonly used options. To change the axes label style, use the graphics option las label style. This changes the orientation angle of the labels:. To change the type of box round the plot area, use the option bty box type :.

To change more than one graphics option in a single plot, simply add an additional argument for each plot option you want to set. For example, to change the label style, the box type, the color, and the plot character, try the following:. To change the font size of text elements, use cex short for character expansion ratio.

The default value is 1. To reduce the text size, use a cex value of less than 1 ; to increase the text size, use a cex value greater than 1.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. It leaves the room for the axis as per ylimbut doesn't fill in the actual axis. I've been through? I know it's a minor thing, but it's exactly the kind of problem I get stuck on for ages, instead of actually working, so any help would be much appreciated! I did initially plot without ylim, but it ends up with an even more bizarre axis with the same problem ; I actually picked my ylim values to give it a nicer spaced axis.

I see you try to set ylim but you give bad values. This will change the scale of the plot like a zoom. For example see this:. Another option is to plot without axes and set them manually using axis and usr :. Simplest solution seems to be specifying the ylim range. Here is some code to do this automatically left default, right - adjusted :. The trick is to use pretty which returns a list of interval breaks covering all values of the provided data.

It guarantees that the maximum returned value is 1 a round number 2 greater than maximum value in the data. In the example 0 was also added pretty c 0, dat which makes sure that axis starts from 0.

Im trying to align the x-axes of a bar plot and line plot in one window frame using ggplot. Here is the fake data I'm trying to do it with.

Align x axes of box plot and line plot using ggplot

If, for example, the y labels on one of the plots take up more space than on the other, even if you use the same axis on each plot, they will not line up when passed to grid. I think this code should produce the plot you want. However, without your exact dataset, I had to generate simulated data.

In linux, you could use awk with fread or it can be piped with read.

You can create a similar plot in ggplot, but you will need to do some reshaping of the data first. Do not use the dates in your plot, use a numeric sequence as x axis. You can use the dates as labels. Your sapply call is applying fun across all values of x, when you really want it to be applying across all values of i. Using data. It, by default, doesn't return no matches though. I'll leave that to you.

Instead, will show an alternate method using foverlaps from data. Assuming that you want to get the rowSums of columns that have 'Windows' as column names, we subset the dataset "sep1" using grep. Then get the rowSums Sub1divide by the rowSums of all the numeric columns sep1[]multiply byand assign the results to a new column "newCol" Sub Given your criteria -- that is represented as 3 and is 20 -- how about dividing by and then rounding towards 0 with trunc.

You can put your records into a data. Given a list of English words you can do this pretty simply by looking up every possible split of the word in the list.

You can alternatively look at the 'Large memory and out-of-memory data' section of the High Perfomance Computing task view in R.

Packages designed for out-of-memory processes such as ff may help you.

Combining the example by Robert and code from the answer featured here: How to get a reversed, log10 scale in ggplot2? Change the panel. For some reason the top and bottom margins need to be negative to line up perfectly. Here is the result A better approach would be to read the files into a list of data. The problem is that you pass the condition as a string and not as a real condition, so R can't evaluate it when you want it to.

Your intuition is correct. You can do it with rJava package. See that blog entry for Here's a solution for extracting the article lines only. Turned out much more complex and cryptic than I'd been hoping, but I'm pretty sure it works. Also, thanks to akrun for the test data. It's generally not a good idea to try to add rows one-at-a-time to a data.R in Action 2nd ed significantly expands upon this material. Many high level plotting functions plot, hist, boxplot, etc.

For example. Many other graphical parameters such as text size, font, rotation, and color can also be specified in the title function. Add a red title and a blue subtitle. Text can be added to graphs using the text and mtext functions. To practice adding text to plots in R, try this interactive exercise.

Other common options are cexcol, and font for size, color, and font style respectively. You can use the text function see above for labeling point as well as for adding other text annotations. Specify location as a set of x, y coordinates and specify the text to place as a vector of labels. The x, y, and label vectors should all be the same length. You can add mathematically formulas to a graph using TEX-like rules. See help plotmath for details and examples.

If you are going to create a custom axis, you should suppress the axis automatically generated by your high level plotting function. Here is a somewhat overblown example. The minor. Add minor tick marks library Hmisc minor. The length of the major tick mark is retrieved from par "tck". Other graphical parameters such as line type, color, and width can also be specified in the abline function. Other common legend options include bty for box type, bg for background color, cex for size, and text.

For more on legends, see help legend. The examples in the help are particularly informative.

Alternatively, the text can be placed interactively via mouse by specifying location as locator 1. Labeling points You can use the text function see above for labeling point as well as for adding other text annotations. Axes You can create custom axes using the axis function.

Reference Lines Add reference lines to a graph using the abline function. Legend Add a legend with the legend function. You can give an x,y coordinate for the upper left hand corner of the legend. You can use locator 1in which case you use the mouse to indicate the location of the legend. You can also use the keywords "bottom", "bottomleft", "left", "topleft", "top", "topright", "right", "bottomright", or "center". Other options.
