You can use the histogram function from the lattice package (standard in 
R) in combination with the print statement. Example:

h = histogram(cars$speed)
h2 = histogram(cars$speed, xlab = "", ylab="")
print(h, more = T)
print(h2, position = c(.05,.65,.5,.95))

The position argument in print gives the bounding box for the lattice 
object. The coordinate system is c(x1,y1,x2,y2) where (x1,y1) is the 
bottom left corner and (x2,y2) is the top right corner. The coordinate 
system runs from (0,0) in the bottom left corner to (1,1) in the top 
right corner.
