Validate and order path data

Description

Internal helper to validate and reorder data within each group according to the order_by aesthetic. Used by stat_ordered_path().

Usage

ordered_path_df(
  data,
  group,
  order_by,
  decreasing = FALSE,
  na_method = c("drop_na", "drop_group")
)

Arguments

data	A data frame containing at least an order_by column (and optionally a group column created by ggplot2).
decreasing	Logical. If TRUE, sort order_by in decreasing order; otherwise in increasing order.
na_method	Character string indicating how to handle missing values in order_by. One of "drop_na" or "drop_group".

Value

A data frame with the same columns as data, but potentially fewer rows (after dropping rows or groups) and with rows reordered within each group.
