Decide which variable to keep

var_to_keep(
  values,
  n_kept = NULL,
  prop_kept = NULL,
  cutoff = NULL,
  maximize = TRUE
)

Arguments

• values: A numeric vector, with one value per variable to keep or discard.
• n_kept: Number of variables to keep.
• prop_kept: A numeric value between 0 and 1 representing the proportion of variables to keep. n_kept and prop_kept are mutually exclusive.
• cutoff: Threshold beyond which (below or above) the variables are discarded.
• maximize: Whether to minimize (FALSE) or maximize (TRUE, the default) the quantity given by values.

Returns

A logical vector indicating if variables are kept or discarded.

Examples

scimo:::var_to_keep(1:5, n_kept = 3, maximize = TRUE)
scimo:::var_to_keep(1:10, cutoff = 8, maximize = FALSE)
