Side by side? Check out help(layout) and help(par). For the latter,
the mfcol and mfrow arguemnts are what you're after. Follow the commands
that are used when you type
par(ask=TRUE)
example(hist)
par(ask=FALSE)
Another possibility is the lattice library histogram() function.
par(ask=TRUE)
library(lattice)
example(histogram)
par(ask=FALSE)
Two overlaid in the same plot?
<opinion>
Ugly. Use density plots instead, whenever possible.

The density() function provided is good for this, and so is the sm
library's sm.density() function.
par(ask=TRUE)
example(density)
par(ask=FALSE)
Cheers
