R/pkgDesc.R

In mmaechler/sfsmisc: Utilities from 'Seminar fuer Statistik' ETH Zurich

##' A slightly more convenient version of packageDescription()
##' 1. returns named character vector; no other attributes
pkgDesc <- function (pkg, lib.loc = NULL, fields = NULL, ...) {
    pd <- packageDescription(pkg, lib.loc=lib.loc, fields=fields, drop=FALSE, ...)
    file <- attr(pd, "file")
    struct(class = "Dlist", c(unlist(pd), c(file=file)))
}

##' useful: e.g. as  sapply( pkgs, pkgBuilt)
pkgBuilt <- function(pkg, lib.loc = NULL, ...) pkgDesc(pkg, lib.loc=lib.loc, fields = "Built", ...)
