Thank you for the package, I find it very useful!
There is an error when using step_dummy with two or more variables and one of them have NA (not sure if it is the expected behaviour).
Error message relates to differing number of rows which is hard to understand which is the problem. Especially if you have a long or complex recipe.
I attach a reproducible example.
library("recipes")
library("dplyr")
data(okc)
okc <- okc[complete.cases(okc),]
# Two variables to dummy -> Works fine
okc$sunny_location <- sample(c("Florida", "Barcelona", "California"), nrow(okc), replace = TRUE)
rec <- recipe(age ~ ., data = okc)
dummies <- rec %>% step_dummy(diet, sunny_location)
dummies <- prep(dummies, training = okc)
dummy_data <- bake(dummies, newdata = okc)
# Variable with some missing values -> Not clear error
okc$sunny_location <- sample(c("Florida", "Barcelona", "California"), nrow(okc), replace = TRUE)
# Add some missing values
okc$sunny_location[1:5] <- NA
rec <- recipe(age ~ ., data = okc)
dummies <- rec %>% step_dummy(diet, sunny_location)
dummies <- prep(dummies, training = okc)
dummy_data <- bake(dummies, newdata = okc)
# Error in data.frame(..., check.names = FALSE) :
