How to count the number of parameters in a function
You can use list(...):
Myfunc<-function(...)
{
d<-list(...)
n<-length(d)
## Other instructions
return(n)
}
## Example:
var1<-runif(20)
var2<-rnorm(20)
var3<-rpois(20, 2)
Myfunc(var1, var2, var3)
Hope this helps,
Clem.

In the above function I have a variable number of parameters (N>2). How can
I count how many parameters have been entered?
Any help appreciated
