labels in hist and ranges of an axis

Hi, Carol!

How is it possible to change the character size of labels in a histogram 
(labels parameter in hist)?

See

?par

-> cex.axis

How is it possible to display the ranges of an axis in 3 significant 
digits?

See

?axis

and its argument "at" together with

?signif
