[R] aov and missing values

[Pedro J. Aphalo]

I am learning R, and although I have looked in the documentation, I may
be asking something obvious. Sorry, if that is the case. 

In a split-plot design if there is a missing subunit summary gives me a
table with two rows for the same factor, one in the error within section
and one in the section using error between units. With no data missing
the table is "normal". How does one interpret the table when data is
missing?, or is it that aov cannot cope with missing values in this
case?

Thanks in advance for any help.

Pedro.

The model I am using is of the form "y ~ A * B * C + block +
Error(A/B)", I tried the simpler model "y ~ A * B + block + Error(A)"
with the same result.

The behaviour is the same in Version 1.1.1 and Version 1.2.0 Under
development (unstable) (2000-10-11). If it matters, I am using Windows.
