[R] relationship between two factors

[Greg Snow]

The 'table' function will give you the simple counts.  Plotting a table
with the 'plot' function gives common charts for this.  The 'CrossTable'
function in the gmodels package creates the table along with additional
information.  There are a lot of other functions for creating/working
with tables depending on what you are trying to do.

Hope this helps,
