Colleagues,
(Running R 2.7.0)
I have a script that I want to delete as it completes execution. The
penultimate line of the script (before the quit command) is:
file.remove("Scriptname")
The script is executed as:
R --no-save < Scriptname
In OS X and Linux this is successful and returns:
file.remove("x")
[1] TRUE
and the file is deleted
In Windows XP, it returns:
[1] FALSE
and the file is not deleted.
I realize that this is an OS issue rather than an issue with execution
of the command. Is there some means to delete the script from within R?
Not in an OS that does not allow open files to be deleted. (Not the whole
truth for WIndows, but true of the mechanism used to implement redirection
in the compiler used for R.)
You could modify Rscript to do so (it does not use re-direction).
