I've encountered a very bizarre problem with my R scripts. I had a bunch saved in a folder, and after reinstalling R (which was itself having some issues), the rather large scripts I had can easily open in R, but appear to have no text on them (this is despite it clearly labeled as an R document in the folder and being 26kb). Yet when I upload my scripts in a message on Slack, it appears perfectly fine.
Here is what my R script looks like presently:
And this is what it should look like:
I'm thinking it has something to do with the way R is reading the text in the script, but I couldn't find any answers online that were helpful. I would greatly appreciate any advice, as I dont' want to have to recreate all of these using Slack of all things...
I figured it out with some tinkering and it was a rather simple fix that mirrored what I thought the issue was. Apparently my RStudio program was set to read the text in CP936 format. I set it to system default:
And viola! My text is now back!

it's been a few days that im trying to run my Rmd on Kaggle, but it simply doesn't work.
The main reason (I guess) is that, somehow the console is reading the code as an R code, but im sure that I'm using Rmarkdown.
Therefore, the console reads a Text line as a code line, giving me the code error below:
Also, i tried to copy and edit other's people markdown, but i keep getting the same error line.
You can check my code here: https://www.kaggle.com/badluckmath/kernel4c85aae59c/edit/run/39891200
He's working perfectly on my Rstudio.
I'm looking for a huge help here, please!
I've been stuck with this for a week!
If i press the buttom to run code, it will simply give me this error message.
For that, i still don't know the solution. But since this is a premade Rmarkdown and i knew that it works, i simple used the Save (Commit) options and at the end, it worked.
ctrl+R no longer works for executing script lines.
This is not a hardware/keyboard problem.
I have also restarted my PC.
I have tried on a different PC.
I have recently switched from using R to using RStudio. I thought this may have something to do with it, so I opened and resaved the script in RStudio, to no effect.
Furthermore, I have created an R-Project folder and have copied the files, including the script in question, into it. Then I started R-Studio and opened the project.
I would like to post my sessionInfo(), but do not know how to do that without executing the command.
Keep in mind that I only use R for stats purposes. I don't know much about informatics or other types of programming etc., so please try to keep it simple for me. Thanks!
In addition to the solution offered above, in Rstudio, Ctrl + Enter does not work if the chunk is broken in .Rmd files.
For example, if you press CTRL + Enter on the following line (2+2), it won't work:
```{r}
2+2
``
The chunk should end three Backtick characters, not two.
The problem was that the script file (for some reason unkown to me) did not have the correct extension (.R). When I added that to the script file extension, it worked fine again.
I ran into a very weird problem: my R code for generating a plot only works if I type it into the console but not when I ran it inside the script (with Ctrl+Enter command)... It's the same problem with all plots (regular plots or ggplots). Also I tried it on two different computers and the same thing happened. Anyone have any idea why this is happening?
One possible reason: I installed the newest version of Rstudio on both computers so it might be an issue with the version. The exact same code worked before on an older version of rstudio...Could this be it? If so, how can I fix it?
I think I figured out what the problem was: the setting in the new version of Rstudio has a default option of outputting the plots inside the Rmarkdown script (at the very end of the script). And that's why I wasn't seeing them. You could change the setting such that it outputs in the console.
Try dev.off() to reset the graphics device.
This helps with a lot of weird graphics behaviour.
Probably too late for the original poster... However, I just ran into the same problem after installing an R update. The way I fixed it was to go to preferences, R markdown, and turn off "show inline output". For me, it was just coming out at the bottom of the chunk instead of in the plot window like I wanted. Hope that helps someone!
I just ran into this problem. I mistakenly put my plot() command inside the r markdown setup chunk. I moved it to its own code chunk and it ran as expected.
I am attempting to automate the insertion of JPEG images into Powerpoint. I have a macro done for that already, except using R would be infinitely better for my purposes.
The package R2PPT should do this, I understand. However, I cannot use it. For example, when I try to use PPT.Open, I understand I can do it two different ways by calling method = "rcom" or method = "RDCOMClient". Using the latter, R will always crash, sending an error report to windows. Using the former, it tells me I need to install statconnDCOM , before giving the error:
Error in PPT.Open(x) : attempt to apply non-function.
I cannot install statconnDCOM freely, as I wouldn't call this work non-commercial. So if there isn't a way to get around this issue, are there at least some free alternatives to R2PPT so that I can save several hours of manual work with a simple R code? If there is a way for me to use R2PPT, that would be ideal.
Thanks!
Edit:
I'm using R version 2.15 and downloaded the most recent version of R2PPT. Powerpoint is 2007.
Do you have administrative privileges on this machine?
There is an issue with package RDCOMClient. It needs permissions to write file rdcom.err in the root of drive C:. If you don't have privileges to write to c:, there is a rather cumbersome workaround:
Close R
Create "c:\temp" folder if it doesn't exist.
Locate on your hard drive file rdcomclient.dll. It usually placed in \R\library\RDCOMClient\libs\i386\ and in \R\library\RDCOMClient\libs\x64\ (you need to patch file which corresponds your Windows version - 32 bit or 64 bit). It's recommended to make backup copy of this files before patching.
Open rdcomclient.dll in text editor (Notepad++, for example -http://notepad-plus-plus.org/)
Find in file string c:\rdcom.err - it occurs only once.
Go into overwrite mode (usually by pressing "Ins" key). It is very important that new path will have the same number of characters as original one. Type C:\temp\e.rr instead of c:\rdcom.err
Save the file.
Now all should work fine.
Arguably not an answer, but have you looked at using Sweave/knitr to render your presentations in LaTeX using something like Beamer? (As discussed on slide 17 here.)
Wouldn't help any with getting JPGs into a PowerPoint, but would certainly make putting R-output (numerical or graphical) into a presentation much easier!
Edit: if you want to use knitr (which I recommend), here's another reference.
I am having some problems with my clipboard contents when using R. When I run my scripts/commands in tinn-r, very often I would get something that I had ran earlier pasted onto my R Console instead of the command that I have just selected.
To get over this, I would go to my clipboard and delete its content(text/syntax). However, the same text/syntax that I had just deleted would re-appear on my clipboard and would again appear on my R Console when trying to run a different syntax from my tinn-r.
Good luck. Tinn-R seems to be a particularly buggy way of interacting with R. Though it takes some effort to set up, the StatET plugin interface from Eclipse has been working way better for me than Tinn-R ever did.
