Hi,
I am having trouble with syntax for a for loop. Here is what I am
trying to
do.
class=c(rep(1,3),rep(2,3),rep(3,3))
out1=rnorm(length(class))
out2=rnorm(length(class))
out3=rnorm(length(class))
data=data.frame(class,out1,out2,out3)
dat.split=split(data,data$class)
for(i in 1:3){
sub[i]=dat.split[i]
}
However, the for loop doesn't work. I want to assign each split to a
different data object.
Why? What's wrong with leaving them in a list that split() provides.
In that form you can easily use lapply() and start your 12 step
program away from for-loop addiction.
Better yet, how I could assign each class to a
separate object and skip the splitting?
