When the user passes a formula to `fit()`

*and* the underlying model function
uses a formula, the call object produced by `fit()`

may not be usable by
other functions. For example, some arguments may still be quosures and the
`data`

portion of the call will not correspond to the original data.

repair_call(x, data)

x | A fitted |
---|---|

data | A data object that is relavant to the call. In most cases, this
is the data frame that was given to |

A modified `parsnip`

fitted model.

`repair_call()`

call can adjust the model objects call to be usable by other
functions and methods.

fitted_model <- linear_reg() %>% set_engine("lm", model = TRUE) %>% fit(mpg ~ ., data = mtcars) # In this call, note that `data` is not `mtcars` and the `model = ~TRUE` # indicates that the `model` argument is an `rlang` quosure. fitted_model$fit$call#> stats::lm(formula = mpg ~ ., data = data, model = ~TRUE)# All better: repair_call(fitted_model, mtcars)$fit$call#> stats::lm(formula = mpg ~ ., data = mtcars, model = TRUE)
