[R] R equivalent of Beaton's Sweep algorithm

[Michael Friendly]

I'm looking for an R equivalent of Beaton's (1964) Sweep algorithim for 
partial inversion of a
matrix by pivoting.

It implemented in SAS/IML as sweep(matrix, indices), described here
http://support.sas.com/documentation/cdl/en/imlug/59656/HTML/default/langref_sect266.htm

and here for python
