[R] getting started, reading listing and saving data

[Patrick Burns]

The 'corner' function is in the spirit (but not the letter)
of what you ask for.  It is a generalization of 'head' and
'tail' which gives the first or last few items in each dimension
of a matrix or higher dimensional array.

It is available in the public domain code on the Burns
Statistics website.
