R help - Nov 2009 - save an object by dynamicly created name

Hi,

I would like to save a few dynamically created objects to disk. The
following is the basic flow of the code segment

for(i = 1:10) {
   m = i:5
   save(m, file = ...) ## ???
}
To distinguish different objects to be saved, I would like to save m as m1,
m2, m3 ..., to file /home/data/m1, /home/data/m2, home/data/m3, ...

I tried a couple of methods on translating between object names and strings
(below) but couldn't get it to work.

Any suggestions would be appreciated.

thanks

Hao

path <- "data";
dir.create(path);

for (i in 1:10) {
  m <- i:5;
  filename <- sprintf("m%02d.Rbin", i);
  pathname <- file.path(path, filename);
  save(m, file=pathname);
}
