R devel - May 2003 - Opening previous workspace in Windows (PR#2890) (fwd)

Filing the response on R-bugs.

It's quite possible that uninstalling R will damage this, but I would have 
expected it to be removed entirely.

Your expectation was correct  - adding "%1" to the open command fixes 
the problem. 

I think it might have happened because I installed the new
version before uninstalling the old version - although the files were 
still associated with the new version so it's a bit odd that it was 
just the second part of the open command that was wrong. However, I 
didn't have the problem on my home computer (WinXP) when I uninstalled 
the old version first so I expect that's where I went wrong.

Thanks for the fix,

Heather

Hi,

I spent some time now trying to understand how functions for the
computation of contrasts

contr.foo(n, contrasts=TRUE)

passed to model.matrix are called. My problem is
that for the computation of some contrasts one needs `n' to be the number
of observations at each level of the factor of interest and for others the
number of levels is sufficient. For example, `contr.treatment' has code
for handling vector valued `n' (and ?contrasts states that `n' may be a
vector).

Where can I find the condition under which `n = nlevel(x)' or `n
table(x)' or how can I define what I would like to see?

Best,

Torsten
