And of course data visualization. Only library I know of is Chart[1] but
I don't like API much.
There is the plot[1] library which provides for updateable plots from GHCi REPL and has a gnuplot-like interface. I wrote it for this very reason, a mathematics/statistics development environment.
It uses Data.Vector.Storable, which provides for compatability with both statistics and hmatrix packages (as well as hstatistics).
I think talking about data frames is a bit pointless unless we specify
what is data frame. Basically there are two representations of tabular
data structure: array of tuples or tuple of arrays. If you want first go
for Data.Vector.Vector YourData. If you want second you'll probably end
up with some HList-like data structure to hold arrays.
