Sequences of Variables for Tuning
This function generates a sequence of mtry values for random forests.
var_seq(p, classification = FALSE, len = 3)
p |
The number of predictors |
classification |
Is the outcome a factor ( |
len |
The number of |
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.
