Error in overscope_eval_next(overscope, expr) : object 'G' not found #58
Description
Thank you for all your efforts in making these libraries available. Much appreciated!
I believe I have found a minimal(ish) reproducible example of an issue I am also encountering.
library(tidyverse)
library(modelr)
smaller <- diamonds %>% filter(carat < 3)
mod_diamond2 <- lm(price ~ carat + color + cut + clarity, data = smaller)
grid <- smaller %>%
data_grid(cut, .model = mod_diamond2) %>%
add_predictions(mod_diamond2)

FWIW, a specific fix to the R for Data Science book is to replace
grid <- diamonds2 %>%
data_grid(cut, .model = mod_diamond2) %>%
add_predictions(mod_diamond2)
with this:
grid <- diamonds2 %>%
data_grid(cut, lcarat = -0.515, color = "G", clarity = "SI1") %>%
add_predictions(mod_diamond2)
Basically explicitly specifying the levels of all factors that are not to be gridded.
