lightoverhead has asked for the wisdom of the Perl Monks concerning the following question:
Monks:
I have a question regarding manipulating a matrix or data frame.
I know manipulating a matrix/data frame in R is pretty easy.
You can index it, subset it, aggregate it by certain categories, get the row/column number and names.
You can also apply function to each row or column.
If you know R, you may know the functions, such as:
subset
with
aggregate
transform
and etc
since, we generally need to apply statistic calculations on a subset of matrix/data frame;we may need some statistical functions/package associated to this package as well
In fact, I want a set of functions which are equivalent to those in R, does anyone know such a package?
Thank you
