Sequences of Variables for Tuning

This function generates a sequence of mtry values for random forests.

Keywords
models
Usage
var_seq(p, classification = FALSE, len = 3)
Arguments
p

The number of predictors

classification

Is the outcome a factor (classification = TRUE or numeric?)

len

The number of mtry values to generate.

Details

If the number of predictors is less than 500, a simple sequence of values of length len is generated between 2 and p. For larger numbers of predictors, the sequence is created using log2 steps.

If len = 1, the defaults from the randomForest package are used.

Value

a numeric vector
