# Determine largest value of mtry from formula.
This function potentially caps the value of `mtry`

based on a formula and
data set. This is a safe approach for survival and/or multivariate models.

`max_mtry_formula.Rd`

Determine largest value of mtry from formula.
This function potentially caps the value of `mtry`

based on a formula and
data set. This is a safe approach for survival and/or multivariate models.

## Arguments

- mtry
An initial value of

`mtry`

(which may be too large).- formula
A model formula.

- data
The training set (data frame).

## Examples

```
# should be 9
max_mtry_formula(200, cbind(wt, mpg) ~ ., data = mtcars)
#> [1] 9
```
