[Rcpp-devel] Fwd: Building and Installing an R package built under RcppArmadillo on Mac OS X

[Steve Lianoglou]

Something is definitely wrong.

My printout goes out to 1 more decimal place than yours:

R> fun(matrix(rnorm(9),3,3))
           [,1]       [,2]       [,3]
[1,]  1.3709584 -0.5646982  0.3631284
[2,] -0.5646982  0.4042683 -0.1061245
[3,]  0.3631284 -0.1061245  2.0184237

R> sesionInfo()
R version 2.13.1 Patched (2011-09-15 r57010)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)
...

And

$ g++ --version
i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664)
