NaNs in Nested Mixed Model
Dear R users,

The background is that I have studied the number of insect nymphs
emerging from replicated Willow genotypes in the field. I have 15
replicates each of 4 Willow genotypes belonging two 2 Willow species.

combining elements in a data frame
Hi all,
I have 2 data frames the first contains a list with repeats of words and an associated response time (RT) measure for each word. The second is a tabulation of each unique word and other information such as the amount and of responses for each word. I need to determine the mean RT for each word and add that as a column in the second data frame.
Any help would be appreciated
Cheers

Request
Dear all,
I am trying to learn R.
Is it possible to find the mean of some rows (of some table) and to put it
in new table.
For example we have following table
date x y z
1 05-23-2001 7 1 3
2 05-24-2001 8 4 5
3 05-24-2001 6 0 0
4 05-24-2001 26 2 6
5 06-19-2001 0 7 0
6 06-19-2001 5 0
