thanks for making me notice that document - I just skipped over it the past

Thanks very much Petr, that one did just fine!
I just wanted to say that it's not that I did no reading at all (in fact I
use a book called R for Stata users by Muenchen/Hilbe and another German
book called Programming in R when you translate the title) - so yes I am
aware that R works quite diff

Hey Petr,
thanks for answering. First to your question: I use rename from the reshape
package.
You are probably right to assume that I do not have a to extensive reading
background in R - basically I had to dive right in (which probably isn't a
good idea, but I could not change that). Having a s

Hey everyone,
I have again a loop question:
After generating the dataset using Jan’s approach from my previous posting
(http://r.789695.n4.nabble.com/Loop-over-several-variables-td4648112.html) I
want to rename the Variables in the new dataset so that all y will be called
tiy. Doing it separately
Oh hey Jan, sorry, I just saw I did not read correctly and mistook your quote
of Don's mail as a signature. So thank's to you for the second posting

Hey Don,
many thanks, I tried that and it works just fine. I have two questions
though:
1. In Addition to generating the t1-t5 (I have five iterations, in fact),
the code will generate an additional ti(without subscript), which seems to
be a copy of ti5. Is that what it should do ( and if yes, wh
Or
ti <- aggregate(dataframename[paste0("y", 1:3)],
by=dataframename["aggregationvar"],
sum,na.rm=TRUE)
which gives you all results in one data.frame.

Hey everybody,
I am looking for a way to loop commands over several variables in a
dataframe. Basically I want to do something like this:
ti1<-aggregate(dataframename$y1,
by=data.frame(dataframename$aggregationvar),
sum,na.rm=TRUE)
This works fine as it is but i wan
