R 1.5.1 on AIX 5.1
I'm trying to get R running on AIX 5.1 with the native AIX compilers, VisualAge C++
5.0.2.0 and XL Fortran Compiler 7.1.0.0. R compiled fine, but in running the test
cases, the base-Ex.R tests fail in the Choleski decomposition with the following:
> x <- matrix(c(1:5, (1:5)^2), 5, 2)
> m <- crossprod(x)
> Q <- chol(m)
Error in chol(m) : NA/NaN/Inf in foreign function call
