When installing R on Linux CentOS 6.2 I get the following:
Error: Package: R-core-2.10.0-2.el5.x86_64 (/R-core-2.10.0-2.el5.x86_64) Requires: libt
The above did not work for me. I had to install tcl.
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm sudo yum install tcl sudo yum clean all sudo yum install R
