Thanks for the additional suggestions. It's even better now:
void handle_winch(int sig){
if(fired)
return;
fired = 1;
char buf[16];
*buf = 0;
if(write(ofd, buf, 1) <= 0)
REprintf("setwidth error: write <= 0\n");
}
static void uih(void *data) {
char buf[16];
if(read(ifd, buf, 16) == 0)
REprintf("setwidth error: read = 0\n");
R_ToplevelExec(setwidth_Set, NULL);
fired = 0;
}
Best,
Jakson

[Rd] Download R
I use Fedora 10. I need to update my computer's R version. I apologise if this has come up before. The Debian and Ubuntu download links appear reasonably up to date. The Suse download links appear almost up to date. Unfortunately, the Fedora download links are from 2008/2009. http://cran.r-project.org/bin/linux/ Should the Fedora links be removed or updated? __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Fedora has, for several years now, offered R via the normal Fedora yum repos. Thus, the RPMs are no longer on CRAN. The same for RHEL via the EPEL. That being said, I presume that you are aware that Fedora 10 was EOL'd back in late 2009. Thus, you have not had any bug fixes, patches, security updates, etc. for 3 years, which tends to obviate the reason for using Fedora, which is a bleeding edge Linux distribution. Fedora only supports a given release for around 18 months and the current stable release is Fedora 17. I would advise you to upgrade your Fedora version. Once you have, you can use: yum install R from the CLI as root to install R. Also, there is a dedicated e-mail list for R on Fedora: https://stat.ethz.ch/mailman/listinfo/r-sig-fedora Any subsequent questions you have about using R on Fedora should be posted there. General R questions should go to R-Help.

There are some recent(-ish) R binaries in the EPEL repositories. I am not at work now and hence cannot check, but I got a new rmp-based machines up to speed a while back when I needed to. Not sure what to do about the CRAN docs though apart from pleading with Martyn or whoever looks after the meta-information there.
