[R] error in Fields TPS function

[Simon Wood]

This may be a irrelevant, but I had some problems using svd() after R
started allowing optimizations that use floating point registers for
temporary variable storage (because these registers are usually longer than
a standard double then some convergence testing tricks can get fooled by
allowing this). Using la.svd() instead of svd() solved the problem.
