Show fitted regression line with visreg interface — br_show_fitted_line • bregr

Provides an interface to visualize the model results with visreg package, to show how a predictor variable x affects an outcome y.

Usage

br_show_fitted_line(breg, idx = 1, ...)

Arguments

breg: A regression object with results (must pass assert_breg_obj_with_results()).
idx: Length-1 vector. Index or name (focal variable) of the model. This is different from idx in br_show_forest_ggstats, only one model is supported to visualized here, so only length-1 vector is supported as idx.
...: Arguments passing to visreg::visreg() excepts fit and data.

Value

A plot

Examples

if (rlang::is_installed("visreg")) {
  m <- br_pipeline(mtcars,
    y = "mpg",
    x = colnames(mtcars)[2:4],
    x2 = "vs",
    method = "gaussian"
  )

  if (interactive()) {
    br_show_fitted_line(m)
  }
  br_show_fitted_line(m, xvar = "cyl")
}
