Hi Gabriel,
I actually want to make renames over thousands of files. But if I am not
able to express the source filename of the rename operation I will not be
able to get the work done. Besides the fact that there are issues I think
that R is qualified for solving my problem by the method how it can handle
long vectors of strings, booleans and also lists.
Kind regards,
Frank

Hi Frank,
I'm hesitant to be "that guy", but in case no one else has brought
this up
to you, having files with a tilde in their names (generally but
especially
on a linux system, where ~ in file names has a very important special
meaning in some cases, as we know) strikes me as an exceptionally bad
practice anyway. In light of that, the solution with the smallest
amount
of pain for you is almost surely to just... not do that. Your
filenames
will be better for it anyway.
There is a reason no one has complained about this before, and while I
haven't run a study or anything, I strongly suspect its that
"everyone"
else is already on the "no tildes in filenames" bandwagon, so this
behavior, even if technically a bug, has no ability to cause them
problems.
Best,
~G

Hi,
yes, I have seen this package and it has the same tilde expanding
problem.
Please excuse me I will cc this answer to r-help and r-devel to
keep the
discussion running.
Kind regards,
