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