Explainer created using DALEX::explain

Value

Updated arena object

Examples

library("DALEX")
library("arenar")
library("dplyr", quietly=TRUE, warn.conflicts = FALSE)
# create first model
model1 <- glm(m2.price ~ ., data=apartments, family=gaussian)
# create a DALEX explainer
explainer1 <- DALEX::explain(model1, data=apartments, y=apartments$m2.price, label="GLM gaussian")
# create live arena with only one model
arena <- create_arena(live=TRUE) %>% push_model(explainer1)
print(arena)
# create and add next model
model2 <- glm(m2.price ~ ., data=apartments, family=Gamma)
explainer2 <- DALEX::explain(model2, data=apartments, y=apartments$m2.price, label="GLM gamma")
arena <- arena %>% push_model(explainer2)
print(arena)
