R package citation, version 0.12.2

A collection of functions to extract citation information from 'R' packages and to deal with files in 'citation file format' (https://citation-file-format.github.io/), 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 = "https://rse.pik-potsdam.de/r/packages"))

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:

install.packages("citation")

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

update.packages()

In case of questions / problems please contact Jan Philipp Dietrich dietrich@pik-potsdam.de.
