Error installing PARTY package in R

Question

Newbie R user here. I wanted to install the party package in RStudio (Ver 0.98.507), but whether I install it directly from the CRAN repository or whether I save the file first and then load it in R, I get the following error message:

> install.packages("party")
Installing package into ‘C:/Users/Linda/Documents/R/win-library/3.1’
(as ‘lib’ is unspecified)
trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.1/party_1.0-15.zip'
Content type 'application/zip' length 731049 bytes (713 Kb)
opened URL
downloaded 713 Kb

package ‘party’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\Linda\AppData\Local\Temp\~~~~~~~\downloaded_packages
> library("party", lib.loc="C:/Users/Linda/Documents/R/win-library/3.1")
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  object 'vI' not found
Error: package or namespace load failed for ‘party’

I am unable to interpret the error message. Every other package download and installation has worked so far though (caret, tree, rpart) so I am confused why this is not working.

Install "multcomp", then "party"

install.packages("multcomp")
library(multcomp)
install.packages("party")
library(party)
