Any function call prefaced by fn$ allows the use of formulas as functions

In that case enter this and then press the Change button

Since it appears to happen in an example you could put

while Rcmdr would only have the essential packages as dependencies.

strapply in the gsubfn package matches a regular expression and passes
each back reference as a separate argument to the indicated function,
in this case paste. Any number of back references may be used. Here
is an example where there are more than 9:

That is usually done with trunc rather than cut since in the case of a
time series we normally don't want a factor result (which is what cut
would give):
trunc(tt, "secs")
trunc(tt, "mins")
# etc
trunc.POSIXt does not support the "30 secs" syntax but trunc.times in
the chron package supports simi
Even though its not hard to convert files, I think it would be better
if R could directly handle different line endings since R tends to be
used in a cross platform way and its common to have files of different
line endings that originated from different systems.

Its also difficult to know about demos unless you specifically issue a
demo(package = "mypackage") command. It would be nice if these were
listed too.
Note that the NEWS and/or ChangeLog file are listed on the package's
CRAN page such as:
http://cran.r-project.org/package=zoo
but the demos a
In the case of R itself and the Windows platform this might usefully
be placed into the Rgui help menu.

Try this:
debug(stats:::ar.yw.default)
and then run the ar function to step through the ar code so you can
see the results line by line and understand what it is doing at a very
