error in the example

[pbiecek]

I was trying to execute an example for modelStudio

library("dime")
library("DALEX")

titanic <- na.omit(titanic)
set.seed(1313)
titanic_small <- titanic[sample(1:nrow(titanic), 500), c(1,2,3,6,7,9)]

model_titanic_glm <- glm(survived == "yes" ~ gender + age + fare + class + sibsp,
                         data = titanic_small, family = "binomial")

explain_titanic_glm <- explain(model_titanic_glm,
                               data = titanic_small[,-6],
                               y = titanic_small$survived == "yes",
                               label = "glm")

new_observation <- titanic_small[1:10,-6]

modelStudio(explain_titanic_glm, new_observation[1,])

but this ends with

> modelStudio(explain_titanic_glm, new_observation[1,])
  |                                                                        |   0%Error in ceteris_paribus.default(x, data, predict_function = predict_function,  :

This error came from ingredients package. It should be fixed now. You can download the newest version from github: devtools::install_github("ModelOriented/ingredients").

Thanks, this helped
