Get CV segments
Get cross-validation segments that have (as far as possible) the same ratio of all classes (if classes are present)
cvseg(x, fold = 7, seed = NULL)
x |
a factor, character or numeric vector that describes class membership of a set of items, or, a numeric vector indicating unique indices of items, or, a numeric of length 1 that describes the number of items to segment (without any classes) |
fold |
the desired number of segments |
seed |
randomization seed for reproducibility |
a list where each element is a set of indices that defines the CV segment.

seg <- cvseg(iris$Species, 10) sapply(seg, function(s) table(iris$Species[s])) cvseg(20, 10)
