factor outcome - factor predictor

Code
  class_test <- prep(step_lencode_bayes(recipe(x2 ~ ., data = ex_dat), x3,
  outcome = vars(x2), verbose = FALSE, options = opts), training = ex_dat,
  retain = TRUE)
Condition

Code
  new_values_ch <- bake(class_test, new_data = new_dat_ch)
Condition
  Warning in `bake()`:
  ! There was 1 column that was a factor when the recipe was prepped:
  * `x3`
  i This may cause errors when processing new data.

factor outcome - character predictor

Code
  class_test <- prep(step_lencode_bayes(recipe(x2 ~ ., data = ex_dat_ch), x3,
  outcome = vars(x2), verbose = FALSE, options = opts, id = "id"), training = ex_dat_ch,
  retain = TRUE, options = opts)
Condition

numeric outcome - factor predictor

Code
  set.seed(8283)
  reg_test <- prep(step_lencode_bayes(recipe(x1 ~ ., data = ex_dat), x3, outcome = vars(
    x1), verbose = FALSE, options = opts), training = ex_dat, retain = TRUE)
Condition

Code
  new_values_ch <- bake(reg_test, new_data = new_dat_ch)
Condition
  Warning in `bake()`:
  ! There was 1 column that was a factor when the recipe was prepped:
  * `x3`
  i This may cause errors when processing new data.

Works with passing family

Code
  class_test <- prep(step_lencode_bayes(recipe(outcome ~ ., data = ex_dat_poisson),
  x3, outcome = vars(outcome), verbose = FALSE, options = c(opts, family = stats::poisson)),
  training = ex_dat_poisson, retain = TRUE)
Condition

Code
  new_values_ch <- bake(class_test, new_data = new_dat_ch)
Condition
  Warning in `bake()`:
  ! There was 1 column that was a factor when the recipe was prepped:
  * `x3`
  i This may cause errors when processing new data.

case weights

Code
  class_test <- prep(step_lencode_bayes(recipe(x2 ~ ., data = ex_dat_cw), x3,
  outcome = vars(x2), verbose = FALSE, options = opts), training = ex_dat_cw,
  retain = TRUE)
Condition
Code
  junk <- capture.output(ref_mod <- rstanarm::stan_glmer(formula = x2 ~ (1 |
  value), data = transmute(ex_dat_cw, value = x3, x2), family = binomial(),
  na.action = na.omit, seed = 34677, chains = 2, iter = 500, weights = wts_int, ))
Condition

bad args

Code
  step_lencode_bayes(recipe(~., data = mtcars), outcome = vars(mpg), verbose = "yes")
Condition
  Error in `step_lencode_bayes()`:
  ! `verbose` must be `TRUE` or `FALSE`, not the string "yes".

bake method errors when needed non-standard role columns are missing

Code
  bake(rec_trained, new_data = ex_dat[, -3])
Condition
  Error in `step_lencode_bayes()`:
  ! The following required column is missing from `new_data`: x3.
