autoplot.SensIAT_within_group_model: Plot a 'SensIAT_within_group_model' Object

In SensIAT: Sensitivity Analysis for Irregular Assessment Times

Plot a SensIAT_within_group_model Object

Description

This creates a line plot for a SensIAT_within_group_model object. The horizontal axis represents time, and the vertical axis represents the expected marginal outcome given the sensitivity parameter alpha.

Usage

## S3 method for class 'SensIAT_within_group_model'
autoplot(object, ...)

Arguments

object	A SensIAT_within_group_model object.
...	currently ignored

Value

A ggplot2 object.

Examples

# Note: example takes a few seconds to run.

object <-
    fit_SensIAT_within_group_model(
        group.data = SensIAT_example_data,
        outcome_modeler = fit_SensIAT_single_index_fixed_bandwidth_model,
        id = Subject_ID,
        outcome = Outcome,
        time = Time,
        knots = c(60,260,460),
        End = 830,
        alpha = c(-0.6, -0.3, 0, 0.3, 0.6),
        intensity.args=list(bandwidth=30)
    )

    # Title not included
    ggplot2::ggtitle("SensIAT within group model") +
    # Nor are bounds on reasonable values of alpha
