Hi,
I'm just wondering what is the best way to read CSV data file
into Mir (2d array) ndslice? Esp. if it can parse date into
int/float.
I searched a bit, but can't find any example.
Thanks.
It probably can't hurt to try the simplest approach first.
`std.csv` can return an input range that you can then use to
create a ndslice. Offhand, I don't know what D tools are an
alternative to `std.csv` for reading CSVs.
ndslice assumes homogenous data, but you can put the Dates (as
Date types) as part of the labels (as Data Frames). However,
there's a bit to be desired in terms of getting that
functionality integrated into the rest of the package [1].
