Question

I’m trying to install Rcpp on Ubuntu 10.04 and getting this error (which implies that it doesn’t exist):

> install.packages("Rcpp")
Warning in install.packages("Rcpp") :
  argument 'lib' is missing: using '/home/vadmin/R/i486-pc-linux-gnu-library/2.10'
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘Rcpp’ is not available

I have a working R instance and have installed many other packages.

Edit

Now I’m getting this error when running R CMD build Rcpp on the source code off svn:

** building package indices … Error : running Stangle on vignette
‘/home/vadmin/src/R/rcpp/pkg/Rcpp/inst/doc/Rcpp-modules.Rnw’
failed with message: invalid value for
‘lang’ : cpp ERROR: installing package
indices failed
* removing ‘/tmp/Rinst3041838816/Rcpp’ ERROR Installation failed.

Answer 1

A few things:

• thanks for your interest in Rcpp 🙂

• it has been on CRAN as Rcpp for years; if you get a Rcpp not available error then you are looking at a bad CRAN mirror and I suggest using a different one

• Ubuntu also has their Rcpp version of the Rcpp Debian package so you could just do ‘sudo apt-get install r-cran-rcpp’ (but that may be a dated version, alas)

In general, Romain and I suggest for Rcpp questions to come to the rcpp-devel list.
