Hi All,
I am no longer with TIBCO and hope to be able to contribute more directly

I just got a new Windows laptop (i7, 10th generation CPU), installed
'Windows Subsystem for Linux 2' and then installed Ubuntu 20.04 and

Perhaps the parser should warn if you use return() at all. It is rarely
needed and is akin to the evil 'GOTO' statement in that it makes the flow
of control less obvious to the reader.

The call to system() probably is an internal call used to delete the
session's tempdir(). This sort of failure means that a potentially large
amount of disk space is not being recovered when R is done. Perhaps
R_CleanTempDir() could call R_unlink() instead of having a subprocess call
'rm -rf ...'
To make the comparison more complete, all.equal.environment could compare
the parents of the target and current environments. That would have to be
recursive but could stop at the first 'top level environment' (the global,

there.

One advantage of the new pipe operator over magrittr's is that the former

Trying to recover from running out of memory probably

be nicer if the example() function could also check for
correctness, and the above method doesn't allow for that.)

Valgrind reports a slew of memory leaks when R closes
after using View(), but it didn't show any use of freed

This would take care of the problem that subset(data.frame,select=-name)
only lets you omit columns.
The mail had a version of [.data.frame (for Splus 2.1?) that
implemented this, although, if it is to be used it should be
implemented in the most primitive [ code so all m
insert a backslash.
I've seen code in package:gdata that depends on this behavior but I did
not see it described in help(gsub). It describes using
replacement="\\" to put a matched subpattern into the output,
but not the fact that replacement="\\" is equivalent t
