R help - Feb 2012 - comparing vectors with condition

Hi

I have two vector

x=c(10,30,40,50)
total=c(20,20,0,10)

Var_exceeding_total=sum(as.numeric(x> total))

This will compare the vectors x and total a gives the result.

if i want to compare only if the y > 0 .
can we apply condition in the comparison ?
 

-----
Thanks in Advance

sum(ifelse(x*total!=0, as.numeric(x> total), 0))
