Passing parameters in a user defined function to another function using ...
Hi,
It's easy, just carry the arguments in '?' forward to where you expect to pass them along.
mynumbs<-function(x,y,z=5,...){
numbs<-sort(sample(y,z, ...))
for (i in 1:(x-1))
numbs<-rbind(numbs,sort(sample(y,z, ...)))
print(numbs)
}
Cheers,
Ben

Hi R Experts,
How do you get the ... to work in a user-defined function such as the one I have below?
For example if I want to pass replace=TRUE to the sample function.
# This is a sample function that generates x rows of z numbers out of y. Basically a lottery style data set.
mynumbs<-function(x,y,z=5,...){
#x should be a scalar indicating number of rows
#y & z are passed to sample function
#in the future will add option to output as data.frame instead of matrix
numbs<-sort(sample(y,z))
for (i in 1:(x-1))
numbs<-rbind(numbs,sort(sample(y,z)))
print(numbs)
}
