[Rcpp-devel] Now 38 CRAN packages using Rcpp

[baptiste auguie]

Awesome indeed, congratulations!

RcppArmadillo has 8 offsprings on CRAN, RcppEigen and RcppGSL none so far.

AP <- available.packages(contrib.url("http://cran.r-project.org"))

## more concise count
## length(grep("Rcpp", AP[,"Depends"]))
## sum(grepl("Rcpp", AP[,"Depends"]))

depends = data.frame(pattern= c("Rcpp", "RcppArmadillo",
                       "RcppEigen", "RcppGSL", "rJava"))

library(plyr)
pl <- mlply(depends,  grep, x = AP[,"Depends"])
arrange(ldply(pl, length), -V1)
