Nice! Thank you.

I hope this is the start of more R code being ported!

If you like to write the full path like "std.math.isNaN", then 
you can also use static imports.


Perhaps it's worth adding pre/post-conditions to the functions.

The indentations probably have a mix of tabs and spaces and 
seem messed up.


Is gamma_cody better/worse than std.mathspecial.gamma?


gamma_cody is special variant for bessel functions.
