[R] 'save' saved object names instead of objects

[Sarah Goslee]

This is one of the rare cases in R where you don't want to save
the return value. You loaded d.eta, and then promptly overwrote it
with the return value, which is just the name of the object.

> ls()
character(0)
> d.eta <- array(0,dim=c(3,3,200))
> dim(d.eta)
[1]   3   3 200
> save(d.eta, file="deta")
> rm(d.eta)
> ls()
character(0)
> load("deta")
> ls()
[1] "d.eta"
> dim(d.eta)
[1]   3   3 200
> # and compare
> rm(d.eta)
> ls()
character(0)
> d.eta.name <- load("deta")
> ls()
[1] "d.eta"      "d.eta.name"
> dim(d.eta)
[1]   3   3 200
> d.eta.name
[1] "d.eta"
