When trying to install the caret package on Ubuntu 14.04 LTS 32 bit I received the following warnings

Solution

You need to install all of the dependencies prior to installing the 'caret' package.

install.packages(c('lme4', 'pbkrtest', 'BradleyTerry2', 'car', 'caret'))

The above code should fix the issue.

Or you could use:

install.packages('caret', dependencies = TRUE)

You can then attempt to install the 'nloptr' package using the above command.
