make_envelope_graph {simITS}

Make envelope style graph with associated smoothed trendlines

Description

This method builds a ggplot object with the trendline and prediction envelope. It can be customized after the fact by adding more ggplot layers via normal ggplot "+" syntax.

Usage

make_envelope_graph(envelope, t0, ylab = "Y", xlab = "month")

Arguments

envelope

The result of a 'process_outcome_model()' call, i.e. dataframe with columns of original data, imputed data and, potentially, smoothed data.

t0

Last pre-policy timepoint. Will draw vertical line here.

ylab

Y label of plot

xlab

X label of plot

Value

Returns (does not yet display) a ggplot plot object containing the time series along with extrapolation and prediction envelope. This plot can be augmented and changed via standard ggplot commands.

Examples

data( "mecklenberg" )
t0 = 0
envelope = process_outcome_model( "pbail", mecklenberg, 
                                  t0=t0, R = 10, 
                                  summarize = TRUE, smooth=FALSE )
make_envelope_graph(envelope, t0=t0, ylab = "Proportion given bail") +
  ggplot2::labs( title="Sample ITS plot")
data( "mecklenberg" )
t0 = 0
envelope = process_outcome_model( "pbail", mecklenberg, 
                                  t0=t0, R = 10, 
                                  summarize = TRUE, smooth=FALSE )
