Passing parameters in a user defined function to another function using ...
4 messages · Lopez, Dan, Ben Tupper, Richard M. Heiberger
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)
}

numbs <- rbind(numbs, sort(sample(y, z, ... ))) See ?Reserved which sends you to 'Introduction to R' Rich

Thanks Ben.
I feel really dumb. I did enter '...' in my sample function in another version of this function. But I just realized I had only done it for the second occurrence of the sample function and not the first.
