R help - Jul 2006 - summary.formula table questions

Question 1) I am using the summary.formula function, from the Hmisc,
package, to construct a table of the mean establishment rates of multiple
plant ecotypes.  I do not want the count (N) columns included in the table.
Is there a way to suppress that statistic? 

Question 2) The table will have multiple columns, each representing a
different location. Is there a way to include Tukey's HSD at the bottom of
each column?

Thank you.

Matt

Matt,

For 1) where method='reverse' or 'cross' you can do
s <- summary( ... )
print(s, prn=FALSE)

For method='response' the latex.summary.formula.response method has a 
prn argument and it would not be too hard to add one to 
print.summary.formula.response.

Your best bet for 2) is probably to use summary.formula with 
method='reverse' and to write a new 'test' function for
continuous
response variables that includes some kind of across-column summary.
