I had to test an R-application that works with Chinese character. Just for fun,
I took one character from WikiPedia, pasted it into R-Gui, and pressed enter.
Rgui smoothly closed down without saying anything else.
I am aware, this is not serious

Hi,
I'm writing a C function that has to call a R function with multiple
arguments. I've read the relevant section in Writing R Extensions, and
searched the R site, mailing lists as well as rseek. I managed to call
the function, but I'm now having trouble creating the argument list.
I tried to cr
Try PrintValue(R_fcall):
function(x,y)match.call()
(list(x = 10, y = 12))
You want a pairlist of length 1+nargs, not a pairlist of pairlists. Here
is one way to do it (there are many)
#include
SEXP foo(SEXP fn, SEXP elmt1, SEXP elmt2, SEXP rho)
{
SEXP R_fcall, args, ans,s;

Please follow the posting guide before reporting bugs! You have failed
to even follow the instruction from the page you got the image from -
this is long fixed (the update was posted 5 days after the affected R
2.6.2 release).
Cheers,

Yes, there's a change from R 2.6.2 to 2.7.0 that might have
been unintended and hence a bug.
The short version is this
setClassUnion("OptionalPOSIXct", c("POSIXct", "NULL"))
as(Sys.time(), "OptionalPOSIXct", strict=FALSE)
which now gives

The columns of the model matrix are all orthogonal. So the problem
lies with poly(), not with lm().

y = rnorm(15)
z <- model.matrix(lm(y ~ poly(x, 12)))
x = rep(1:5,3)

Actually, this may be a useful feature! It allows calculation of a
basis for the orthogonal complement of the space spanned by
model.matrix(lm(y ~ poly(x,12)). However, the default ought surely to
be to disallow df > k-1 in poly(x,df), where k = length(unique(x)).

I haven't parsed the source to fully understand
the 'normalization constants' returned in the
poly output component
attr(,"coefs")$norm2
but notice that the first 6 are non-zero and
the last 8 are smaller than machine precision.
Some kind of useful warning to the user could
ensue upon evaluatio

While trying to fix swig & R2.7 I actually discovered that there is a
bug in R 2.7 causing a crash (so R & swig might actually work):
the bug is in ./src/main/gram.c line 3038:
} else { /* over-long line */
fixthis --> char *LongLine = (char *) malloc(nc);
if(!LongLine)
