Not so. The default in data.frame() is to convert character vector to
factors, but there are many w
While I do not know how to handle this on the C level, I know that
you do not have characters in data frames, everything is factors
instead. Internally they are coded as a number of integer levels,
with the levels having labels (which is the character you see). So eg

Hello,
I'm trying to fetch a data frame through the C API,
and have no problem doing this when all columns
are numbers, but when there is a column of
strings I have a problem. On the C-side the
function looks like:
SEXP myfunc(SEXP df),
and it is called with a dataframe from
the R side with:
.Cal
R-Devel,
all.equal.factor gives a warning message when comparing vectors of
factors of different lengths. I suspect this to be unintentional as I
believe tests of valid factors should be comparable without a warning.
For example:
> x1 <- as.factor(LETTERS)
> x2 <- as.factor(LETTERS)[1:10]
> all.eq

Does anyone see a nice portable way to detect --- from inside R ---
if R is using its own BLAS or not?
{ And ideally, if not, can R find out which ``kind'' of
(optimized) BLAS it does run? }
And the same for LAPACK ?
One way of getting a partial answer seems to be

Thanks for the info.
It's interesting that R can load the library using a network share naming
convention but that the library path has the "\" replaced with "/". I guess
it's too much to ask for R not to muck with the file name provided (for a
variety of reasons). My package works fine except
For the record: The error below has been resolved. As Professor Ripley
said, it was a compiler problem. Upgrading to a more recent gcc rpm
(gcc-3.4.5-2) and its dependencies made the errors go away.
Thanks,

This is not supported: network shares are a Windows 'feature' and not part
of R's conception of file paths. The specific issue here is dirname(),

You can always map shares to network drives, and that is common practice
