Dear expeRts,
Now i want to know how to implement an Unary operator like i++ in cpp's
synax form.
e.g. 2++ will let 2 be 3 , a<-2 ,a++ ,will let a be 3
I tried this :
'%++%'<-function(x){
x<<-x+1
}
but it have problem, the biggest one is it seems the function need
twoparams like a%++%b , how to write a function needing just one param?
TKS !
Just ***DON'T***. The "++" operator is useful only for those wish to
write code which is obscure to the point of incomprehensibility. It
makes C and its offspring "write only" languages.
If you are going to use R, use R and don't pollute it with such
abominations.
cheers,
Rolf Turner
