I tried installing the plyr package individually but I got the same error

InternetOpenUrl failed: 'The operation timed out'

while installing the dependency package Rcpp and plyr also failed

Answer 1

Try and see if the following syntax works for you:

install.packages("ggplot2", dependencies = TRUE, repos = "http://cran.rstudio.com/")

Mirror names can be changed via "repos".
