Carol,
it is not clear to me which function histogram() you use (package lattice,
package histogram ...?), but -- if it is not a lattice function -- a quick
hack _might_ be to use
par( cex = 2)
or whatever magnification you wish followed by a reduction of cex.axis,
cex.labels etc. according to your needs.
If you used plot.histogram() take a look at its code by
graphics:::plot.histogram
and you will see (at the end of the body of the function) that there is no
"direct" way (i.e., through arguments of the function) of changing
anything regarding the "data labels" except the one way mentioned above or
writing your own function plot.histogram().

cex.axis changes the size of the axis label. I want to change the size

histogram. What we obtain by histogram(...,labels=T)

Subject: Re: [R] 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
