Apache Mahout

I followed this tutorial. Mahout seems to be an easy way to test Machine Learning algorithms using the Java API.

But I would use this  this R code instead of the one shown in the tutorial to convert the MovieLens dataset to CSV format.

r<-file("u.data","r")
w<-file("u1.csv","w")

while( length(data <- readLines(r)) > 0 ){
	writeLines(gsub("\\s+",",",data),w)
}
