Hello, 'yum search R' returns an impossibly-long list. So I tried 'yum search R.x86_64' and 'yum search R-2.3.0' and few others to no avail. (Google revealed that R package does exist in kbsingh repository.) However, 'yum install R' did offer to install the correct package. Can someone enlighten me as to why did the searches failed or generated a hugh list of alternatives, while the install hit right on the mark? Thanks, Itay FWIW: cat kbsingh-CentOS-Extras.repo [kbs-CentOS-Extras] name=CentOS.Karan.Org-EL$releasever - Stable gpgcheck=1 gpgkey=http://centos.karan.org/RPM-GPG-KEY-karan.org.txt enabled=1 baseurl=http://centos.karan.org/el$releasever/extras/stable/$basearch/RPMS/ # Need a ftp mirror ? uncomment the line below, & disable the one above # baseurl=ftp://rpm.karan.org/pub/kbsingh/el$releasever/extras/stable/$basearch/RPMS/ #== 2006-07-10 <itayf at fastmail.fm> protect plugin config ==# protect = 0 exclude = *.i386 *.i586 *.i686 includepkgs = darcs darcs-server prozilla R
