RSiteSearch("Breslow"), which will perform a search of the e-mail list archives and other online documentation, reveals this post:

http://finzi.psych.upenn.edu/R/Rhelp02a/archive/50202.html

which in turn leads to this code:

http://www.math.montana.edu/~jimrc/classes/stat524/Rcode/breslowday.test.r

There is also code for the Woolf test in ?mantelhaen.test

Further searches can be conducted using help.search("Keyword"), which will search your installed set of packages.

See ?help.search and ?RSiteSearch for more help on these.
