r - Error: package or namespace load failed for ‘car’ -

i'm unable load car package in r. tried reinstalling using

install.packages("car",dependencies=true) 

both r , rstudio. tried installing quantreg advised in post , installing again. installation appears successful, can't load program.

here's complete error:

error in loadnamespace(j <- i[[1l]], c(lib.loc, .libpaths()), versioncheck = vi[[j]]) : there no package called ‘pbkrtest’
in addition: warning message: package ‘car’ built under r version 3.2.3
error: package or namespace load failed ‘car’

instead of update.package(checkbuilt = true) should update.packages(checkbuilt = true)
