Function creates binary matrix, to be used in aspect_importance method. It
starts with a zero matrix. Then it replaces some zeros with ones. If
sample_method = "default" it randomly replaces one or two zeros per
row. If sample_method = "binom" it replaces random number of zeros
per row - average number of replaced zeros can be controlled by parameter
sample_method = "f". Function doesn't allow the returned matrix to
have rows with only zeros.
get_sample(n, p, sample_method = c("default", "binom"), f = 2)
| n | number of rows |
|---|---|
| p | number of columns |
| sample_method | sampling method |
| f | frequency for binomial sampling |
