##### 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

##### Examples

```
# NOT RUN {
var_seq(p = 100, len = 10)
var_seq(p = 600, len = 10)
# }
```
