Because it is a single-precision subroutine (that is what the leading
's'
means), and R does not use single precision.

No, because R does not use single precision.

I think you should rethink why you are using single precision routines
with R. If you need to, you need to ship the routines you need with the
package, as e.g. fastICA does, for there need not be any 'external Lapack
library'.
