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

In reply to Can someone suggest a package with functions of manipulating matrix or data frame as the functions were applied in R? by lightoverhead
