Hello,

the extra memory. Since it's a power CPU server that m

Thank you for the reply Peter.
I've compiled R from source using the following:
./configure --host=powerpc64-power5-linux-gnu
--build=powerpc64-power5-linux-gnu '--with-blas=-framework blas-3.1.0-11'
and after I've made R I get this:
> .Machine$sizeof.pointer
[1] 4
meanwhile uname -a prints

Peter,
First off, as you may have guessed, I don't compile many 64 bit programs so
thanks again for the help. I'll revert back to powerpc64-unknown-linux-gnu
which is the default for -build and -host.
Here's the gcc information
[hostname]:/ # which gcc
/usr/bin/gcc
[hostname]:/ # gcc -dumpmachi
Hi,
src/library/methods/src/methods_list_dispatch.c has the following code
which is part of the definition of R_dispatchGeneric:
/* get its class */
SEXP arg; int check_err;
PROTECT(arg = R_tryEval(arg_sym, ev, &check_err));
if(check_err)

Hi,
If df is a dataframe, its last column can't be deleted using "[<-", but
other columns can be deleted this way.
Example:
> (df <- df0 <- data.frame(x = 1:3, y = 4:6, z = 7:9))
x y z
1 1 4 7
2 2 5 8
3 3 6 9
> df[, "z"] <- NULL
Error in x[[jj]] : subscript out of bounds
> df[, 3] <- NULL

Hi,
I'm trying to write a function to return an R vector which points
directly to a contiguous subset of another vector, without taking a
copy. Since SEXPREC is a header followed by the data, rather than the
header plus a pointer to the data, I'm not sure what I'm trying to do is
possible. Is t
