count the number of argument of a function
Dear All:
I am wondering whether there is a way to read and assign the number of
arguments of a function inside this function.
### For example
fun<-function(x1,x2,x3,...){
m<- number of arguments
}
### e.g.
fun<-function(x1,x2,x3){
m<- number of arguments
### m =3 in this case
}
### e.g.
fun<-function(x1,x2,x3,y1,z1,z2){
m<- number of arguments
### m =6 in this case
}
with thanks
Steve
