An R function to turn a vector of package names into a bibliorgraphy
View bibify_pkgs.R
#' Generate a bibliography of packages
#' This function creates an output bibliography from an input character vector
#' of package names. The primary use case for this function is when working
#' with other authors and you need to provide a reference list of packages used.
#' @param pkgs A character vector of packages
#' @param csl A csl file used to format the output bibliography. Good place to
#' look for these is \url{}
#' @param append_bib Existing \code{.bib} file to append package citations to.
