Compute x-axis visit levels for categorical/bar plots

Returns the ordered visit labels as they appear on the plot axis, including duplicate-handling expansions for categorical data (e.g. "WEEK 6" becomes "WEEK 6 01", "WEEK 6 02" when a patient has multiple observations at that visit).

Usage

get_plot_visit_levels(param_ids, df_measures, plot_type = "categorical")

Arguments

param_ids

Character vector of parameter_id values.

df_measures

Data frame as returned by prepare_measures().

plot_type

Either "categorical" or "bar".

Value

Character vector of visit labels in timepoint_rank order.
