evals and house_prices datasets and updated get_regression_table() and get_regression_points() functions.Details:
get_correlation() function to omit $ syntax and return a data frameinfer::rep_sample_n() instead of our own defined version, as this function is now included in inferevals, house_prices, tactile_prop_red, pennies_sample and mythbusters_yawn datasetsget_regression_summaries()newdata argument to get_regression_points().
