Hi there, Often times, I would run R in the terminal when the task is computationally intensive and a nice-looking UI is less desired. However, pasting a large chunk of code into the terminal often times ends up being messed up. In Python, the same problem would happen, however, iPython provides a small functionality called magic word such as %paste that can help paste the code neatly into the terminal. I'm wondering if there's a similar functionality in R. Thanks, -- *Xu Tian* [[alternative HTML version deleted]]

I highly recommend ?source.
You can use source("clipboard") on windows, but creating complete
files that define functions and feeding those complete files to source is a
significant step in developing reproducible analyses. Whenever you find yourself
pasting more than a couple of lines (one or two function calls) you should be
making another function. However, even if you resist making functions you should
be making a habit of sourcing complete files from disk rather than passing large
chunks of code.

If you are on Windows, I believe that would be: R.exe CMD BATCH MyCode.R possibly having to specify the $PATH to R.exe. See ?BATCH for additional information and Appendix B in An Introduction to R: https://cran.r-project.org/doc/manuals/r-release/R-intro.html#Invoking-R Regards, Marc
Thanks, Marc and Jeff, for the advice of running a file of R code rather than a chunk of R code. Just thought it would be nice to have a feature like this so that there's still a sense of interaction in running R code. It was a random idea and I think using "source" would achieve the same goal.
