Hi All,
I have TCL/Tk installed from the latest DMG image for R 3.2.2 I will upgrade to
R 3.2.3 as soon as the DMG is available). I’d like to *completely remove*
Tcl/Tk as installed by the DMG image. I can get a list of files from:
pkgutil --files org.r-project.x86_64.tcltk.x11
but the list is long it it looks like it is going to be tedious to remove all
the files one by one (I could remove the directories but I could only do that
once I am sure nothing else is there from another source).
Is there a smarter way of achieving my goal?
You could edit the list to remove directories such as
usr
usr/local
usr/local/bin
usr/local/include
usr/local/lib
usr/local/lib/pkgconfig
usr/local/man
usr/local/man/man1
usr/local/man/man3
usr/local/share
usr/local/share/man
usr/local/share/man/mann
then use a (shell? R?) script on the list.
Indeed. My only concern is whether these directories have been created by the
R DMG installer and have *never* been used by any other program to put some
Tcl/Tk related file (or not just those, especially in the ‘man’ directories!).
Hence my desire to remove the files in the list, so I can ascertain post-hoc
whether the directories are empty or not (and thus remove them).
So use unlink() below.

Also, the R-devel manual sources contains the commented block:
@c Maybe too dangerous for naive users.
@c The second could be uninstalled by an @R{} script like
@c @example
@c lis <- system2("pkgutil", "--files org.r-project.x86_64.texinfo", stdout =
TRUE)
@c setwd("/")
@c file.remove(rev(lis))
@c @end example
@c @noindent
@c run as the owner of @file{/usr/local}.
where file.remove will remove empty directories (and rev() ensures they are
emptied first).
