In modelenv: Provide Tools to Register Models for Use in 'tidymodels'

set_fit() cannot be called multiple times

Code
  set_fit(model = "tape", mode = "partition", eng = "stats", value = list(
    interface = "formula", protect = c("formula", "data"), func = c(pkg = "stats",
      fun = "lm"), defaults = list()))
Error <rlang_error>
  The combination of 'stats' and mode 'partition' already has a fit component for model 'tape'.

set_fit() errors with wrong `model` argument

Code
  set_fit("light")
Error <rlang_error>
  Model `light` has not been registered.

Code
  set_fit(model = c("bear", "rabbit"), mode = "partition", eng = "stats", value = list(
    interface = "formula", protect = c("formula", "data"), func = c(pkg = "stats",
      fun = "lm"), defaults = list()))
Error <rlang_error>
  Please supply a character string for a model name (e.g. `'k_means'`).

set_fit() errors with wrong `mode` argument

Code
  set_fit("camcorder")
Error <rlang_error>
  Please supply a character string for a mode (e.g. `'partition'`).

Code
  set_fit("camcorder", c("classification", "regression"))
Error <rlang_error>
  Please supply a character string for a mode (e.g. `'partition'`).

Code
  set_fit("camcorder", NULL)
Error <rlang_error>
  Please supply a character string for a mode (e.g. `'partition'`).

Code
  set_fit(model = "camcorder", mode = "not partition", eng = "stats", value = list(
    interface = "formula", protect = c("formula", "data"), func = c(pkg = "stats",
      fun = "lm"), defaults = list()))
Error <rlang_error>
  'not partition' is not a known mode for model `camcorder()`.

set_fit() errors with wrong `engine` argument

Code
  set_fit("dice", "partition")
Error <rlang_error>
  Please supply a character string for an engine name (e.g. `'stats'`).

Code
  set_fit("dice", "partition", c("glmnet", "stats"))
Error <rlang_error>

Code
  set_model_engine("dice", "partition", NULL)
Error <rlang_error>
  Please supply a character string for an engine name (e.g. `'stats'`).

Error <rlang_error>
  The `fit` module cannot be NULL.

Error <rlang_error>

set_fit() errors if engine doesn't match
