tapply with unequal length of arguments
...possible to use tapply(x,y,mean) if not all groups of x by y are
of the same length (for example if you have one missing observation)?
I tried tapply(x,y,mean,na.omit=T) but it doesn't work!

print() from within a function - Windows specific? (PR#7584)
...ol returns to the command window. A test code
could be:
for(i in 1:10){
for(j in 1:1000){
for(k in 1:1000){}
}
print(i)
}
I once ask a linux / unix user and he was not able to reproduce the problem.
Best regards

type III sums of squares in R
...fit
A,B, and AB (as 3 main effects) in 3 different sequential models with
each one of them in the end once. For the term in the end you then get
type III SSQ which seem to be correct.

Change positions of columns in data frame
Hi all,
Probably a simple question, but I just can't find a simple answear in the older threads or anywhere else.
I've added some new vectors as columns in a data frame using cbind(). As they're all put as the last columns inte the data frame, I would like to move them to specific positions. How do you do to change the position of a column in a data frame?
