Hi Neha, One sure cure for divide by zero is to omit zeros in the denominator variable.
num<-sample(0:10,20,TRUE) denom<-sample(0:10,20,TRUE) zeros<-denom == 0 num[!zeros]/denom[!zeros] If you don't want to lose those data and there are no negative values, you could add a small number to all denominator values if that would still give useful output.
