This function generates a sequence of mtry
values for random forests.
var_seq(p, classification = FALSE, len = 3)
The number of predictors
Is the outcome a factor (classification = TRUE
or numeric?)
The number of mtry
values to generate.
a numeric vector
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.
