R package citation, version 0.8.2

CRAN status DOI R build status codecov r-universe

Purpose and Functionality

A collection of functions to extract citation information from ‘R’ packages and to deal with files in ‘citation file format’ (, extending the functionality already provided by the citation() function in the ‘utils’ package.


For installation of the most recent package version an additional repository has to be added in R:

options(repos = c(CRAN = "@CRAN@", pik = ""))

The additional repository can be made available permanently by adding the line above to a file called .Rprofile stored in the home folder of your system (Sys.glob("~") in R returns the home directory).

After that the most recent version of the package can be installed using install.packages:


Package updates can be installed using update.packages (make sure that the additional repository has been added before running that command):
