Using repositories other than CRAN with miniCRAN

Although the package name miniCRAN seems to indicate you can only use CRAN as a repository, you can in fact use any CRAN-like repository.

This vignette contains some examples of how to refer to different package repositories, including CRAN, alternative mirrors of CRAN, R-Forge as well as BioConductor.

To simplify the code to show the salient features, we use a little helper function, index() that is a simple wrapper around available.packages():

# Wrapper around available.packages ---------------------------------------
index <- function(url, type = "source", filters = NULL, head = 5, cols = c("Package", "Version")) {
  contribUrl <- contrib.url(url, type = type)
  p <- available.packages(contribUrl, type = type, filters = filters)
  p[1:head, cols]

Using CRAN

The URL for the master mirror in Austria:

CRAN <- ""

Using a different mirror

You can also point to any other mirror, for example the stable version hosted by Revolution Analytics:

revoStable <- ""
revoMirror <- ""

Using R-forge

R-forge has CRAN-like structure:

rforge <- ""

Using BioConductor

Although BioConductor has a different preferred install mechanism, the underlying repository structure is also CRAN-like:

bioc <- local({
  env <- new.env()
  evalq(source("", local = TRUE), env)
bioc[grep("BioC", names(bioc))]
