I have an R script file `foobar.R'. I want to run the script, and then leave me in the interactive R session when it's done.
Calling
$ Rscript foobar.R
or
$ R -e "$(cat foobar.R)"
does not provide the desired behaviour, since the R interpreter immediately quits when the script is done.
Currently, I am using
$ R
> source("foobar.R")
The problem is that the second command needs to be typed inside the R interpreter - I would like to do it all in a single line form the shell, so that I can set an alias for it, or simply recall a previous command with the up-arrow.
In essence, I am looking for something like Python's
$ python -i foobar.py
Does such an option exist for R?
