Hi David,
Thanks for your answer.
But I don't really see how I can extend it with my real data.
The thing is that I have more than 3 names and 1 value for each name.
Moreover, each is different from one run to another. That is why I was
trying with a modification of names(). Also to be noted is that I
simplified the "name" in assign(); I actually have 2 other variables
that will be pasted to create the name.
Here is my code (I kept only what is important for that part):
----
library(WRS)
seq.num <- seq(7,10,1) #column (variable) indexes to be used as
numerical variables
# fac2list() separates the data from file[,k] into groups from levels in
file[3] and store into list mode.
for(i in 1:length(seq.num)) {
k <- seq.num[i]
name.num <- names(file)[k]
assign(paste(names(file)[3], name.num, sep="_"), fac2list(file[,k],
file[3]))
names(paste(names(file)[3], name.num, sep="_")) <-
levels(factor(file[[3]])) #that line doesn't work, but I would like
something in this direction
}
----
Thanks in advance for your help.
Regards,
Ivan

I have a follow-up question:
I use assign() to store some value in my paste()-created object as
suggested:
for (i in 1:3) {
assign(paste("object", i, sep=""), c("a", "b", "c"))
}
Then I would like to change the names of the elements of that object
within the loop. Since it is all in a loop, I cannot give the name of
the object manually by doing something like: names(object1) <-
c("tooth", "bone", "species").
The only thing I can give to names() is paste("object", i, sep=""),
which doesn't work.
Any idea of how to do it?

+ assign(i, c("tooth"="a", "bone"="b", "species"="c") )
+ }
> object1
tooth bone species
"a" "b" "c"
Thanks in advance

Upon reading it yesterday, it appeared as it would have required
some serious testing and there was no data on which to do any work.
You were clearly not taking the time to isolate the problem and
construct a dataset. But who knows? When you say "What I want to do
is. ... ,I would like the name of the list to be created in the loop
too", maybe all you needed was to be pointed to was:
?assign
But if that were the case, then you lost most of your audience along
the way with a bunch of unneeded and obscure code.
