(depreciated) Add model predictions (including fitted values and confidence intervals) to a plot

Description

This function has been renamed. Please use add_error_envelope instead.

Usage

add_model_predictions(
  x,
  CI = list(),
  fCI = "poly",
  CI_gp = list(col = scales::alpha("lightgrey", 0.8), border = FALSE),
  add_fitted = TRUE,
  fitted_gp = list(col = "black", lwd = 1, lty = 1)
)

Arguments

x	A numeric vector defining the x values at which fitted values/CIs will be plotted.
CI	A named list with fitted values (optional) and lower and upper CIs (i.e. CI$fit, CI$lowerCI, CI$upperCI). This can be created by list_CIs.
fCI	A character defining the method by which CIs will be added to a plot: as lines ("lines") or as a shaded polygon ("poly"). For large datasets, fCI = "lines" is much faster.
CI_gp	A named list of graphical parameters for CIs. If fCI = "lines", then two nested lists can be included to specify the lower and upper CI lines differently, if desired (see Examples).
add_fitted	A logical input defining whether or not add the fitted line.
fitted_gp	A named list of graphical parameters for the fitted line (passed to lines).

Details

The function is designed for continuous explanatory variables (i.e., adding regression lines and CIs to a plot). See add_error_bars for discrete explanatory variables.

Value

The function adds model predictions to a plot.
