Manually installing CRAN to access xtable library

I tried installing CRAN into R using

install.packages("cran")

The code would run but in the console the following message would appear

  package ‘cran’ is not available for this version of R

How can I install cran on my version of R?

Solution

CRAN is a repo not package, have you tried this:

install.packages("xtable",repos = "http://cran.us.r-project.org")
