Dear list,
I have a question and I'm going to give an example of my problem
f<- function(d1, d2, d3)
{
d<- d1*d2/d3
return(d)
}
v1<- 1
v2<- 2
If I try
f(v1, v2, v3)
Error in f(v1, v2, v3) : object "v3" not found
I obviously got the above error message.
I would like to add something to my function to allow me to get a certain
value (say zero)
if one of the arguments is not provided (in this case v3).
Thanks in advance
J
