Managing a Local R Repository

November 10, 2011

I will be teaching a workshop on R and LaTeX at NEAIR in just under a month. One of the issues I will encounter is a lack of Internet access. I also work with restricted data from NCES which requires the computer to be secured including no network access. As such, I need to manage software from removable media. I have written some functions that will create a local repository, update a local repository, and install packages from the local repository. These are included as part of a new R package irutils that I am developing in support for the workshop and accompanying document/book, Introduction to R an LaTeX for Institutional Research. The irutils is being hosted on Github but the R script file can be retrieved directly here: Here are the functions available (note that the createLocalRepos function can take a long time to run as it will download approximately 2GB of data for source alone):

  • createLocalRepos(local.repos = “~/MyLocalCran”, type=”source”)
  • updateLocalRepos(local.repos = “~/MyLocalCran”, type=”source”)
  • local.available.packages(local.repos = “~/MyLocalCran”, type=”source”)
  • local.install.packages(c(‘devtools’, ‘ggplot2′), local.repos = “~/MyLocalCran”, type=”source”)
