A language technical question.

If I have 100 objekts in a folder and I prefer not to load them manually I wonder how I do this in R if using a for-loop. I was thinking initially to do something like this: infiles <- dir(pattern=".RData")
For sure you mean infiles <- dir(pattern = "\\.RData")
for(i in length(infiles))
This won't work. I'd try for(i in 1:length(infiles)) or much better: for(i in seq(along = infiles))
{
load(infiles[i])
paste("kalle", i, sep="") <- saveLoadReference
Whatever saveLoadReference is ... try
assign(paste("kalle", i, sep=""), saveLoadReference)
Please note that it might be a good idea to use a list "kalle" with
elements corresponding to the different "saveLoadReference" objects. So
that you don't mess up you workspace with many objects ....

}
But the line """paste("kalle", i, sep="")""" does not do it for me. I
get the error message "Error: Target of assignment expands to
non-language object"
The thing that I do not master is how to create a name in a for-loop
that I can assign something to. And I want to be able to change that
name as the loop goes on. I want to create in this case
kalle1
kalle2
kalle3
...
kalle100
and they should all represent the objects that I opened with
load(infiles[i])
Best regards
