Some time ago, I posted a note about what I considered to be a bug in
axis.POSIXt() for R 2.8.x, relating to whether timezones in the data are
obeyed on the axes. A link to that note, and to a quick and helpful
response, is at the following URL

I have been trying to compile the earth Multivariate Adaptive
Regression of Splines package as a standalone application under Linux
(x86_64 kernel-2.6.27.21 openSUSE 11.1) with gcc 4.3.2.
The package compiles without problems from within R as an R module and
I get the following linker error:

Perhaps this is the intended behavior, but I discovered that unsplit
throws an error when it tries to set rownames of a variable that has
no dimension. This occurs when unsplit is passed a list of
data.frames that have only a single column.
An example:
df <- data.frame(letters[seq(25)])

sure, but this does not, in any way, make it less strange that gsub is

There is something to be said for taking all of these functions,
including the original RSiteSearch, out of utils and putting them in
the new RSiteSearch package. These are the sorts of things that will
get revised frequently, and this way (I think) we won't have to bother
