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.
