[BlindRUG] Using Rterm with Rmarkdown

Fri Aug 4 18:15:17 UTC 2017

Robin,

I have tried before to set up emacs to program in c++, but couldn't successfully get it to work. How would I set it up to use languages like java, c++, python, r, and sas (if possible)?

Thank you,
Nicholas

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.

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.

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?

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.

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?
