[BlindRUG] Using Rterm with Rmarkdown

[Robin Williams]

Hi,

Sorry to bang on about this, but I'd just like to point out how easy it is to copy and paste output when working in Emacs. One can simply arrow around as usual (there's no need to use the Jaws cursor), and use the standard Emacs selection and copy commands. This is another reason why I'm such a fan of the Emacs environment.

Cheers,
Robin

Hi Nicholas,

No, copy and paste is not easily achieved from the terminal mode of operation.

Perhaps the easiest way to get error messages in editable text might be to run the code as a script using a batch process.

If you save the script as MyScript.R and then use MakeBatch(“MyScript.R”), (NB this is a BrailleR function so the package must be loaded) you will have a batch file called “MyScript.bat” in the current working directory. If you click on that file in the file browser (Windows explorer for example) then the script will be processed in a clean R session and the output file MyScript.Rout will be created. The error will be readable in this plain text file.

HTH

Dr. Godfrey,

In rterm, I may run a piece of code and then get an error from it. Then I may want to copy and paste that error into google to understand it better, but I have tried pressing many buttons on the computer without success. I can highlight the error with the arrow keys, but then I can't do control c to copy it. Is this not a feature in rterm?

Thank you,
Nicholas

Hello Nicholas,

RStudio comes with its own version of Pandoc so it will find it even if the full version is not on the system path.

I recommend you grab a copy of pandoc and install it separately. The most recent version I installed created a folder for pandoc under program files as against older versions that made a folder under my user profile. This newer version also updated the system path variable for Windows so that it will be visible to all other software.

As a consequence, I recommend that everyone update to a more recent version of pandoc to make life simpler all round.

I’m not sure about your other question. Surely the commands you want are in the R markdown file being compiled (?) You might need to explain what you’re doing a little more to get the best out of me on this one. <smiles>

Hello,

Question 1: For rmarkdown in rterm, I am getting the following error when I render a file "Error: pandoc version 1.12.3 or higher is required and was not found." I did the pandoc_available() command in rterm and got false. I did the same command in rstudio and got true. It seems like I have it, but not in rterm. How can I fix this if possible?

Second Question: In rterm, I can copy and paste the current code line I am typing in. Rterm won't let me copy previous errors or lines that have already been run. Is there a way to fix this?

Thank you,
Nicholas
