factors in glm
Is there any logical reason why glm prints out the labels of factor
levels after variable names when baseline contrasts (contr.treatment)
are used but the codes for the levels when mean contrasts (contr.sum)
are used? Jim

eager to learn how to use "sapply", "lapply", ...
...thinking "how can I improve it ?"
For instance, I have a lot of loops similar to the following one and wonder whether I can replace them with a proper call to a high level R function that does the same:
Nstart <- Nfour/(2^Lev) + 1
Nfinish <- Nstart -1 + Nfour/(2^Lev)
LengLev <- Nfinish - Nstart + 1
NW <- floor(LengLev*N/Nfour)
if(NW > 0){
for(j in Nstart:(Nstart + NW -1)){
Dw <- abs(Y[j])
Rnorm <- Rnorm + Dw^2
}
}
Thank you very much for helping me get better.

Translating lm.object to SQL, C, etc function
This is my first post to this list so I suppose a quick intro is in
order. I've been using SPLUS 2000 and R1.6.2 for just a couple of days,
and love S already. I'm reading MASS and also John Fox's book - both have
been very useful. My background in stat software was mainly SPSS (which
I've never much liked - thanks heavens I've found S!), and Perl is my
tool of choice for
