To further explain my case..
am reproducing one of the examples.from one of contributors' guides..
_______________
attach(ais)
here<- sex=="f"
plot(pcBfat[here]~ht[here], xlab = Height, ylab = % Body fat)
panel.smooth(ht[here],pcBfat[here])
detach(ais)
______________
A condition is in "here",... I am not able to use a similar conditioning as
an argument to a function..
Any suggestions will be highly appreciated!
Thnx..
Santosh
