Brian,

latex() is the generic function, which in turn dispatches one of several methods, based upon the class of the 'object' as the first argument.

To see the specific methods and thus the individual functions that are actually called, use:

> methods(latex)

[1] latex.bystats latex.bystats2 [3] latex.default latex.describe [5] latex.describe.single latex.function [7] latex.list latex.summary.formula.cross[9] latex.summary.formula.response latex.summary.formula.reverse

See ?methods

You can then use the above functions to see the code for the individual methods as it exists within R. Note that this is not technically the source code, which would be contained in the Hmisc tarball on CRAN. The latter would have author comments and other content that will not appear within the R session. However, the code as seen within R is more often than not, sufficient to understand what is happening.

**HTH,
