Examples

# Load package
library(dplyr)

# Prepare example data
data_london_prepared <- data_london %>% 
  filter(variable == "no2") %>% 
  rmw_prepare_data()

# Use the test set for prediction
rmw_predict_the_test_set(
  model_london, 
  df = data_london_prepared
)

# Predict, then produce a hex plot of the predictions
rmw_predict_the_test_set(
  model_london, 
  df = data_london_prepared
) %>% 
  rmw_plot_test_prediction()
