That error goes away if you add

    require("methods", character=TRUE, quietly=TRUE)

in zzz.R before the call to loadRcppModules(). In SVN, we have corrected the
Rcpp.package.skeleton() function (or rather the version of zzz.R it copies).


Gauss once played himself in a zero-sum game and won $50.
