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 <- "https://cran.r-project.org"
index(CRAN)
Your output should look like this (albeit with different packages and version numbers):
Package Version
A3 "A3" "1.0.0"
AalenJohansen "AalenJohansen" "1.0"
AATtools "AATtools" "0.0.2"
ABACUS "ABACUS" "1.0.0"
abasequence "abasequence" "0.1.0"
