R help - Feb 2007 - question about boxplot

Here is a question from an old guy:
 
I want to use the boxplot function as follows:
 
boxplot( p.prop ~ R  + bins )
 
This command makes nice boxplot for the factor "R" crossed with the
factor "bins".
 
I am having alot of trouble getting control of the labels on the X axis. I want
to control it more by specifying what the labels are, controling the
'size' of those labels (by using cex), and then control the rotation of
the character strings of those labels (by using srt or crt).
 
There is a "names" argument to boxplot, but I haven't had much
luck controlling what it prints, the size of the font, and the character
rotation.
 
Can somebody enlighten me on how to do this?
 
Please respond to my work email address: pzs6@cdc.gov
 
Many thanks!

Would you consider an easy way out---an alternative with reasonable  
defaults?

data(ToothGrowth)
bwplot(dose ~ len | supp, ToothGrowth)

Hi R-ers:
 
I asked a question about how to control the axes on boxplot. Here is what
worked:

namz <- c( 
"R=1/Q1" , "R=0/Q1" , 
"R=1/Q2" , "R=0/Q2" , 
"R=1/Q3" , "R=0/Q3" , 
"R=1/Q4" , "R=0/Q4" )

boxplot( p.prop ~ R  + bins , boxwex= .5 , plot = TRUE , axes = FALSE )

axis( side = 1 , at=c(1:8) , labels = namz , tick=TRUE , cex.axis = .8 , las=2 
)
axis( side = 2 , at  =  seq(0,1,.1) , labels = seq(0,1,.1) )
 
My thanks to Steven Tucker, Joerg van den Hoff, and Michal Kubovy for their
suggesions
 
All the best,
