In ingredients: Effects and Importances of Model Ingredients

Select Subset of Rows

Description

Function select_sample selects subset of rows from data set. This is useful if data is large and we need just a sample to calculate profiles.

Usage

select_sample(data, n = 100, seed = 1313)

Arguments

data	set of observations. Profile will be calculated for every observation (every row)
n	number of observations to select.
seed	seed for random number generator.

Details

Note that select_subsample() function is S3 generic. If you want to work on non standard data sources (like H2O ddf, external databases) you should overload it.

a data frame with selected rows

library("ingredients")

small_apartments <- select_sample(DALEX::apartments_test)
