[R] using assign on save?

I have an object which I want to save into an external file, using save, on a time step in loop. In the loop I have an if statment that will save when the appropraite time, t, is reached.
I want to change the object and the name of the saved object to reflect which time step is being written. I can do the file name in save using paste but cannot rename the object.
For example, I want to save object foo at time t = 50 in file "Run.50.Rdata." Furthermore, I want the object in that file to be "foo50."
This is what I'm doing now:
save(foo, file = paste("Run", t, "Rdata",sep="."))
which creates the right file name but obviously doesn't rename the object.
So, I tried assigning the object in the save function.
save(assign(paste("foo", t, sep = ""), foo),
file = paste("Run", t, "Rdata",sep="."))
This crashes. It would also leave a copy of foo50 in the workspace which is messy.
The logic of how to rename the object at a time step, reference it in the save statement and then remove it is eluding me.
Any thoughts on how to proceed?
