how to display plot on rstudio

I have a strange issue with Rstudio: If a script calls ggplot2 functions to display a plot, then using Source to run the script does not produce the plots. If I select the whole script with Ctrl+A, then Run the current line or selection (Ctrl+Enter), then the plot does display. Likewise, typing plotting commands into the console produces correct output.

For example:

library(ggplot2)

p = ggplot(mtcars, aes(wt, mpg))
p + geom_point()

Will only produce output if pasted into console, not if sourced.

There are other questions about this, but neither is helpful:

  • ggplot2 ggsave function causes graphics device to not display plots falsely claims the issue is fixed in newer versions, it has not.
  • RStudio - ggplot not saving first plot when printing and saving multiple plots in a script was closed as a duplicate, yet not only is it not a duplicate, but the dev.off() workaround doesn't work ("Error in dev.off() : cannot shut down device 1 (the null device)")

How can I get Rstudio to display plots when a script is sourced? I am using Rstudio 0.98.1062 and R 3.1.1.

The solution is to explicitly call print() on ggplot object:

library(ggplot2)

p <- ggplot(mtcars, aes(wt, mpg))
p <- p + geom_point()
print(p)

ggplot function returns object of class ggplot; ggplot2 works by overloading print function to behave differently on objects of class ggplot - instead of printing them to STDOUT, it creates chart.

Everything is working well in interactive mode, because R assumes that most of commands are run through print() function. This is for our convenience and allows us to type rnorm(1) and get any visible output. When Run current selection command is used (Ctrl+Enter), RStudio behaves as if each selected line was typed in interactive mode and run. You can verify that by checking your command history in Console pane after running few selected lines.

But this convenient mode is abandoned when file is read by source(). Since this function is intended to run (potentially long and computationally-expensive) R scripts, it is undesirable to pollute STDOUT with low-priority messages. That's why source() by default will output only error message. If you want anything else, you have to explicitly ask for that.

My plots are not showing up in the 'plots' area. I have spent a good amount of time Googling the issue and have tried the following with no luck: updated my RStudio Version (now Version 1.1.383) - 64 bit dev.off() while (!is.null(dev.list())) dev.off() dev.cur() to close devices dev.off(i) with i being 2 devices reviewed my Global Options of Rmarkdown and

though it's a quite old question. I had the same problem and found a quick solution, if you want to use "source" button on R studio edit box.

you can simply turn on "source with echo" (Ctrl + Shift + Enter) and the plot shows as expected

I recently happened on this question and realized that the most up to date way is to call show(p) after creating the plot.

Chapter 7 ggplot2, R has several systems for making graphs, but ggplot2 is one of the most elegant So ggplot(data = mpg) creates an empty graph, but it's not very interesting so I' m not The function geom_point() adds a layer of points to your plot, which creates a in the console, or selecting the function name and pressing F1 in RStudio. The following code seems to always increase memory use. Is there a memory leak? This is an extract of using multiple tabs to display multiple plots. It uses ggplotGlob to create multiple groups of plots. When object_size (output) is used, the value seems to always be increasing, event when 10 tabs 3 groups of 10 plots each and then tab 1 is changed to 1 group of 1 plot. In the full application

If you do need to save data (e.g. it takes half an hour to create a dataset), use the save() and load() functions in your script. That way, anyone reading it (including future you) will know what's going on.

ggplot2 Graphs, One frequently asked question about knitr is how to hide package loading messages. For example, when you library(tidyverse) or library(ggplot2) , you may see  This will delete your current plots in the RStudio Plots Pane. If you have multiple graphics devices open, repeat this command until the output displays null device. Further Help. If the above approaches do not solve your problem, try reproducing outside of RStudio. Use the default interface installed with R such as RGui, R.app, or terminal R.

When I knit to an HTML it works fine and all the plots show up as they are in R. When I try to knit to PDF the plots show up fine, but the title and axis labels are missing.
