I wish to install the VIM package for imputing some missing data in RStudio but I am getting an error with the related e1071 package.
The VIM package installs O.K. but the related e1071 fails for the following reason:
> install.packages("e1071", dependencies = T)
Installing package into ‘C:/Users/John/Documents/R/win-library/3.3’
(as ‘lib’ is unspecified)
There is a binary version available but the source version is later:
binary source needs_compilation
e1071 1.6-7 1.6-8 TRUE
Binaries will be installed
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.3/e1071_1.6-7.zip'
Warning in install.packages :

What do I need to do to install this package?
It looks like you got stuck in between a CRAN update of the e1071 package. When your R session asked what version of e1071 was current, it reported (and cached) version 1.6-7; however, soon after version 1.6-8 was uploaded to CRAN. Because of that, the R session attempted to download 1.6-7, but failed as only 1.6-8 was then available.
Restarting R should clear the local package listing cache and get you on your way.
