Seems to work for me:

> x <- matrix(0,10000,10000)
> object.size(x)
800000112 bytes
> gc()
       used (Mb) gc trigger (Mb) max used (Mb)
Ncells   174104  4.7   741108 19.8   741108 19.8
Vcells 101761938 776.4 113632405 867.0 102762450 784.1
> rm(x)
> gc()
      used (Mb) gc trigger (Mb) max used (Mb)
Ncells 174202 4.7   741108 19.8   741108 19.8
