Repeated failures to install "caret" package (of Max Kuhn)
I thought that this might be relevant: https://stackoverflow.com/questions/28985759/cant-install-the-caret-package-in-r-in-my-linux-machine but it seems that you installed nloptr. I would also suggest doing the install in base R and trying a different mirror. I would avoid installing via RStudio unless you have just started a new R session.

Try installing from somewhere outside of RStudio or reboot and retry in

some weird (buggy?) results but I cannot reproduce to send in an bug report.
Load R and from the command line or Windows RGui try installing. As a
test I just installed it successully with the command
"install.packages("caret")" executed in R (using gedit with its
R-plug-in) and running Ubuntu 14.04

Subject: [R] Repeated failures to install "caret" package (of Max Kuhn)
For an edx course, MIT's "The Analtics Edge", I need to install the
"caret" package that was originated and is maintained by Dr. Max Kuhn of
Pfizer. So far, every effort I've made to try to
install.packages("caret") has failed. (I'm using R v. 3.1.3 and RStudio
v. 0.98.1103 in LinuxMint 17.1)
Here are some of the things I've tried unsuccessfully:
install.packages("caret", repos=c("http://rstudio.org/_packages",
"http://cran.rstudio.com"))
install.packages("caret", dependencies=TRUE)
install.packages("caret", repos=c("http://rstudio.org/_packages",
"http://cran.rstudio.com"), dependencies=TRUE)
install.packages("caret", dependencies = c("Depends", "Suggests"))
install.packages("caret", repos="http://cran.rstudio.com/")
I've changed my CRAN mirror from UCLA to Revolution Analytics in Dallas,
and tried the above installs again, unsuccessfully.
I've succeeded in individually installing a number of packages on which
"caret" appears to be dependent. Specifically, I've been able to
install "nloptr", "minqa", "Rcpp", "reshape2", "stringr", and
"scales". But I've had no success with trying to do individual installs
of "BradleyTerry2", "car", "lme4", "quantreg", and "RcppEigen".
Any suggestions will be very gratefully received (and tried out quickly).
Thanks in advance.
