That's easy.  Assign the return value of  hist() to some
variable, say "fixed", then go in and hack the value of
fixed$counts however you like, and re-plot using plot(fixed).
Example code:

fixed <- hist(rnorm(2000))
fixed$counts <- fixed$counts / 5
plot(fixed)

I confess I didn't quite understand your question the first
time I saw it, so couldn't reply.
