Hi Henrik,
Thank you for this suggestion, it does sound easier indeed!

I've found the answer:
get() is exactly what I need, I completely forgot about this function.
There might be a better way, but that works for me.
I R.utils, there are saveObject() and loadObject(), which allows you
to save and load objects without having to worry about their names.
For example:
library("R.utils");
x<- list(a=2, b=3:40, fcn=rnorm);
saveObject(x, "objs.Rbin");
Then later you can load the list object that 'x' held as whatever you
want, say, 'y', e.g.
library("R.utils");
y<- loadObject("objs.Rbin");
This way you don't "contaminate" the working environment with
variables named according to the file, which sometimes can be a
surprise (since you don't always know what the file contain). Except
from that it works just like save()/load().

Dear users,
I would like to process all the lists from all *.rda files that I have in
one folder.
Up to now, I can load all the *.rda files without any problem.
The problem is when I want to access the list saved within each *.rda file
(only one list per rda file).
Here is my code:
fpath<- "D:/R"
listnames<- list.files(path=fpath, pattern=glob2rx("*.rda"),
full.names=FALSE)
for (i in 1:length(listnames)) {
load(paste(fpath, listnames[i], sep="/"))
z<- list_in_listnames[i] ## here is my problem
**do something on z**
}
It might be really simple, but listnames is a character vector and I
cannot find how to store the values within each element into z.
I think there would be a function to get and use an object with a given
pattern in its name. The pattern itself is no problem, the problem is the
function.
I've tried to look on RSiteSearch but, probably because I couldn't figure
out the keywords, haven't found anything helpful.
Maybe I'm just on the wrong path to do it or missed something obvious...
I hope my question is clear. If not, please let me know what would help
you to understand.
Thanks in advance
Ivan
