Displays a heatmap of missing value frequency across the panel

prepare_missing_values_graph(df, ts_id, no_factors = FALSE, binary = FALSE)

Arguments

df	Data frame containing the data.
ts_id	A string containing the name of the variable indicating the time dimension. Needs to be coercible into an ordered factor.
no_factors	A logical value indicating whether you want to limit the plot to logical and numerical variables. Defaults to FALSE.

Value

A ggplot2 plot.
