SampleMat2: Sample binary vector

Description

SampleMat2 is an internal biomod2 function that can help user to sample a binary vector keeping the same proportion of 0s and 1s than in the initial vector.

Usage

SampleMat2(ref, ratio, as.logi = FALSE)

Arguments

ref

a binary vector

ratio

the proportion of ref to sample

as.logi

logical, if FALSE (default) id of cell will be return; if TRUE, logical vector of same length than ref will be return
