What about http://docs.racket-lang.org/math/ ?

I found a package that advertises being an R-like data frame just today, but haven't yet played with it: https://pkg.racket-lang.org/info/munger
I haven't looked into Racket-math, but this post:

makes me wonder if Racket is really up for non-toy numerics.
In contrast, SBCL uses tagless float arrays, so that array operations tend to be cache friendly. With adequate declarations, numerical code in SBCL tends to very fast (~1-3x C speed). I assume one can do the same with Bigloo and Chicken scheme as well.

This is also the case in Racket.
