explore_target | R Documentation |
Helps to explore the distribution of target variable in either visual or tabular form.
explore_target( setup, type = c("visual", "tabular"), weighted = TRUE, exclude_zero = FALSE, lower_quantile = 0, upper_quantile = 1, n_cuts = 20 )
setup |
Setup object. Created at the start of the workflow. Usually piped in from previous step. |
type |
Character scalar. Either |
weighted |
Logical scalar. Whether the distribution should be weighted. |
exclude_zero |
Logical scalar. Whether to exclude records with zero value of target variable. |
lower_quantile |
Numeric scalar. Lower quantile to include in the distribution analysis. |
upper_quantile |
Numeric scalar. Upper quantile to include in the distribution analysis. |
n_cuts |
Integer scalar. Number of cuts in the printed distribution. More cuts means more detailed view. |
Either a ggplot2 chart or vector of values printed to console.
