I'm trying to install package caret on a remote server. At first, it told me that I didn't have the necessary dependencies (ggplot2, nplotr, ..., BradleyTerry2). I played with the repositories and the mirrors until I was able to install all of the dependency packages except for BradleyTerry 2. Now, when I run install.packages('caret', dependencies=TRUE), I get the following warning message, and the installation fails: 1: In install.packages("caret", dependencies = TRUE) : installation of package ?BradleyTerry2? had non-zero exit status 2: In install.packages("caret", dependencies = TRUE) : installation of package ?caret? had non-zero exit status I read up a bit on the web and I saw that the problem may be that I have package brglm version 0.6-1, which is incompatible with BradleyTerry2. My questions are: 1. Could this be the reason why I'm failing to install BradleyTerry2 (and caret as a consequence)? If not, do you have any idea what else could be the problem? 2. If so, how can I install brglm version 0.5-9? I can only seem to install the newest version.
