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).

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).
