How to erase objects

Hi, I admit that I rather carelessly built lots of large objects and therefore ran out of memory. Most objects, which I have at the moment are now unnecessary, but it would take a lot of time to recreate the last few ones from scratch. So I would like to erase (get rid of) selected objects in order to be able to continue. Does anyone know how I could do this?

You can also use ls() which is alias of objects().

One way is to remove unwanted objects by hand
 rm(a,b,c,d)

Another way is to save the required objects, remove everything and then
load the saved objects.
 save(x,y,z, file="out.rda", compress=TRUE)
 rm( list=ls() )
 load("out.rda")

The second approach allows you to load the objects in a fresh R session,
which is one way to release memory if gc() fails. But which approach you
prefer depends on the number of objects to be removed and saved.
