push_model: Adds model to arena

In arenar: Arena for the Exploration and Comparison of any ML Models

Description

If arena is static it will start calculations for all already pushed observations and global plots. If arena is live, then plots will be calculated on demand, after calling arena_run.

Usage

push_model(arena, explainer)

Arguments

arena	live or static arena object
explainer	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)
