Rather unspecific. Basically you'd need a loop to create the sets, and a way to write them into a file.
You did not specify the format of your data. You might be able to use write, write.table or write.csv and the like. You could also have a look at ?save which allows you to save any R object. You also did not specify how important that filename format is. For example: for(i in 1:5){ #create data someData <- i #create filename filename<-paste("data",i,".dat",sep="") #save data write(someData,filename) } This would make unique filenames but not quite what you wanted. greetings, Jessi On 17.01.2013, at 04:31, Ray Cheung wrote: > Dear All, > > I wrote a function datagen to simulate a dataset.
