   VVaalluuee::

        A call of `gc' causes a garbage collection to take
        place.  This usually takes place automagically without
        user intervention.

        The associated function `gcinfo' sets a flag so that
        automatic collection is either silent (`verbose=FALSE')
        or prints memory use statistics (`verbose=TRUE').

        gc() #- do it now
        gcinfo(TRUE) #-- in the future, show when you do it
        x _ integer(0); for(i in 1:18) x _ c(x,i,x)
        gcinfo(verbose = FALSE)#-- don't show it anymore
