R help - Feb 2018 - copy/paste of large amount of code to terminal leads to scrambled/missing characters

Dear R-users,

This question might not be restricted to R, but I hope that some might have
experienced similar problems and could help me.

When using R, I usually work with a text-editor (textmate2) in which I prepare
the script.
To execute code, I then copy and paste it to an R-session running in the
terminal/shell (on Mac OS).

Unfortunately, when pasting too much code into the terminal (e.g. 60 lines),
some characters are occasionally and randomly scrambled or missing.
For example "col <- ifelse(..." turns into "col < col <
cse(?".

This happens very randomly, is difficult to predict, and while it only affects a
hand full of characters in total, it leads to a lot of errors in the code
execution along the way.
Apparently, it has to do with the buffer size and paste-speed of the terminal.

So far, I could not find any solution to the problem.

Therefore, I wanted to ask; 
Do others here use a similar workflow (i.e. having a text-editor for coding and
using copy/paste to the terminal for code execution) and encountered similar
problems with big chunks of code in the clipboard?
Are there any solutions for this problem, specifically for running R over the
shell?

Thank you very much!

This sounds like a problem with your editor or the OS clipboard support rather
than R. You might get a response here, but R-sig-mac seems more appropriate to
me for such discussion.

Obvious suggestion: use a more capable IDE instead of Textmate2 with
copy/paste.

RStudio is very popular now, but there are many others . Search on e.g. "R
IDE For MAC" to see some alternatives.

Cheers,

Why not use the R bundle for TextMate and run your script directly in TextMate?
You'll get nice output.

And if you want to run R directly and get the output in a .Rout file you can add
a command to the R bundle, create a small script that runs R in batch.
Create a new command in the R bundle, give it an appropriate name  and then put
this in the body of the command:

#!/bin/bash
[[ -f "${TM_SUPPORT_PATH}/lib/bash_init.sh" ]] && .
"${TM_SUPPORT_PATH}/lib/bash_init.sh"

if [[ ${#TM_DIRECTORY} -gt 0 ]]; then
	cd "${TM_DIRECTORY}"
else
    exit_show_tool_tip "Save file first!"    
fi

R CMD BATCH --encoding=UTF-8 --no-save --no-timing ${TM_FILENAME}
mate ${TM_FILENAME}out
