Just as an FYI, I suspect the sudden break is connected to a bug
report I filed some time ago [1], and a subsequent fix by Duncan. Long
story short, the previous behaviour of tcltk was actually buggy. The
fix changed this behaviour to what Peter has explained, with the
unintended consequence of bre
Thanks Peter and Dan for your replies.
After learning a bit more about tcltk and environments etc. I have replaced
Try(n <- evalq(TclVarCount <- TclVarCount + 1, .TkRoot$env))
with
Try(n <- .TkRoot$env$TclVarCount <- .TkRoot$env$TclVarCount +1L)
as you suggest.
It now works for both R-3.1.
Seems unlikely that that particular bug is involved. I seem to recall some
change related to inadvertent variable capture in .TkRoot$env (?). At any rate,
we currently have
> parent.env(.TkRoot$env)
which used to be
> parent.env(.TkRoot$env)
as a result, this won't work any more because R_E
I maintain the package affylmGUI. It works when installed on many
previous versions of R. I have today tested exactly the same code under
R-2.15.3, R-3.0.2, R-3.1.0, R-3.1.1, R-3.1.2 and R-devel.
I have also tested the versions of affylmGUI downloaded by biocLite for
each version of R and the
