Plot results from a univariate splinemixmeta model — plot.splinemixmeta • splinemixmeta

Plot results from a univariate splinemixmeta model

Usage

# S3 method for class 'splinemixmeta'
plot(
  x,
  xvar,
  title,
  xlab,
  ylab,
  ylim,
  linecolor = "blue",
  fillcolor = "blue",
  ...
)

Arguments

x: object of class mixmeta returned from splinemixmeta
xvar: xvar name of variable to plot on the horizontal axis.
title: title to add to the plot
xlab: xlab label for the horizontal axis
ylab: ylab label for the vertical axis
ylim: ylim limits for the vertical axis
linecolor: color for the prediction line
fillcolor: color for the prediction confidence band
...: additional arguments passed to predict.splinemixmeta()

Value

ggplot2 object

Details

This is not a very general plotting function. It is intended to provide a basic feature for visualizing a univariate splinemixmeta fit in a way that:

includes fixed effects and spline terms in the predicted values, with 95% confidence bands
Shows the data points with 95% confidence intervals obtains as +/- 2 times the standard errors (se or diag(S)).
returns a ggplot2 object that can be further updated.
