R help - Jun 2008 - spineplot (graphics package): how to control font size?

I cannot modify the font size of the standard text items for the  
splineplot function
found in the standard graphics package.  Here is a tiny example, in  
which
I try (but fail) to make the main title large.

     tbl = read.table ('http://www.ggobi.org/book/data/tips.csv',  
sep=',', header=T)
     spineplot (table (tbl$DAY, tbl$SEX), main='TIPS', cex.main=3)

None of the other 'cex' parameters seem to work either, but cex.main  
is probably
a sufficient example.

Any tips for me?  Thanks!

None of the cex parameters is listed as a parameter on ?spineplot, so 
presumably they just aren't there.  You will have to plot with blank 
titles, and use title(main='TIPS', cex.main=3) in a following call.

Hi Paul,

Duncan has shown you how to do it. There is often a simpler route that is
worth knowing about. Whether it works depends on how the function was coded. 
In this case it works:

## Example
par(cex.main = 3)
spineplot (table (tbl$DAY, tbl$SEX), main='TIPS')
par(cex.main = 1.2)
spineplot (table (tbl$DAY, tbl$SEX), main='TIPS')

HTH, Mark.
