Re: [Rd] [R] Open a file which name contains a tilde
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,

Re: [Rd] [R] Open a file which name contains a tilde
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

Re: [Rd] [R] Open a file which name contains a tilde
Hi Gabriel,
It may be bad practice, but you don't always have control over the file
name.
E.g. if someone shares a file with a tilde in it -- yes it is simple to
rename but it is extra time, and you might not bother to rename a file
without foreknowledge of this bug in the first place.
Even worse, if someone points you to a read only location on a shared
server, you won't even be able to rename the file, and copying might be
prohibitive if it's a large file.
There are also tilde files created automatically by other programs, notably
microsoft office.

Re: [Rd] [R] Open a file which name contains a tilde
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

Re: [Rd] [R] Open a file which name contains a tilde
Note that R treats tildes in file names differently on Windows and Linux.
On Windows, it is only replaced if it it at the beginning of the line and
is followed by a forward or backward slash or end-of-line. On Linux it is
replaced no matter where it is in the text and ~someUser will be replaced
by someUser's home directory (if 'someUser' is a user with a home
directory).
Hence, if you have a Windows machine that can look at the file system on
your Linux machine you can use file.rename on Windows to change the names.
My inclination would be to use a bash script on Linux to change the names,
but if you are not comfortable with bash try the Windows approach.

Re: [Rd] [R] Open a file which name contains a tilde
On 11/06/2019 4:34 p.m., William Dunlap via R-devel wrote:
Note that R treats tildes in file names differently on Windows and Linux.
On Windows, it is only replaced if it it at the beginning of the line and
is followed by a forward or backward slash or end-of-line. On Linux it is
replaced no matter where it is in the text and ~someUser will be replaced
by someUser's home directory (if 'someUser' is a user with a home
directory).
That's not quite true: On Linux the bug is in the code that uses
libreadline, which you don't have to use. If you just specify
"--no-readline" when you start R, it will be fine on Linux, as far as I
can see.
I wouldn't choose that as the default way to run R (it's pretty
irritating not to have readline support), but it is a workaround for
this bug.
Duncan Murdoch
Hence, if you have a Windows machine that can look at the file system on
your Linux machine you can use file.rename on Windows to change the names.
My inclination would be to use a bash script on Linux to change the names,
but if you are not comfortable with bash try the Windows approach.

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,

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,
