dot-plot_data: Internal Data Plotting Engine

In PowRPriori: Power Analysis via Data Simulation for (Generalized) Linear Mixed Effects Models

Internal Data Plotting Engine

Description

An internal helper function containing the logic to "intelligently" create plots from simulated data. It automatically chooses between spaghetti plots and jitter/point-range plots depending on the specified design and model family.It derives sensible defaults for plot aesthetics from the design, if they are not supplied directly via the plot_sim_model function.

Usage

.plot_data(
  data,
  design,
  formula,
  family,
  x_var,
  group_var,
  color_var,
  facet_var,
  n_data_points
)

Arguments

data	The data frame to plot.
design	The PowRPriori_design object.
formula	An lme4-style formula (e.g. outcome ~ predictor1 * predictor2 + (1 | subject))
family	The model family. Defaults to "gaussian", other possible values are "binomial" or "poisson".
x_var, group_var, color_var, facet_var	Strings specifying variables for plot aesthetics.
n_data_points	The maximum number of trajectories in spaghetti plots.

Value

A ggplot object.
