sapply(Date, is.numeric)
...y to the
bugs.r-project.org website. As far as I can tell, the bug tracking
system hasn't picked this up. Also it looks like the latest "incoming"
bug is dated 25 May 2008, so perhaps others are having difficulty as
well. (cc: r-bugs)
Cheers, Robert

R-developers,
The results below are inconsistent. From the documentation for

Changing function arguments
...t into its component functions, search for FUN and increment one of
its arguments ('x'), then reassemble and return the resulting
expression. However, I haven't been able to come up with a clean way to
do this. Suggestions would be greatly appreciated.
Thanks in advance,

one could download it just as one can download the reference manual or

Indexing Lists and Partial Matching
...check for an
error, and if there is an error substitute NULL (to mimic the "["
behavior). However, I don't really want to start using another indexing
function altogether just to get around this behavior. Is there a better
way? Can I turn off partial matching?
Thanks,
Robert

Changing function arguments to NULL
...them in explicitly:
e.g. alist(x = 5, y = 2, z = 3).
Re-assigning and then re-evaluating output of the match.call() function
might not be the way to go, but I am not sure, and would appreciate any
comments on the best way to set function arguments to NULL before
evaluating.
Thanks,
Robert

Removing terms from formula

Likewise, if both 'y' and 'z' are one-level factors, then the resulting
calculation is simply lm(x ~ 1).
Unfortunately, I have not been able to come up with an elegant solution
to this. Any suggestions would be greatly appreciated.

The following can't be right,

Then rw2001:

Plotting text with lattice

Also, note that I'm hoping to use text to label interesting points in a
levelplot, but am using the above xyplot as an example.

as.data.frame: Error in "names<-.default" (PR#7808)
...r [1]
Note, that while the extra (unused) arguments in FUN seem unnecessary,
as well as the odd indexing, the problem disappears when I remove the
extraneous values. Unfortunately, I have not found a more elegant way to
present this problem, but hopefully this code will be helpful.
