add_legend(
  object,
  labels = NULL,
  section_labels = c("Lines", "Phases"),
  case = 1,
  position = "right",
  datalines = TRUE,
  statlines = TRUE,
  phases = TRUE,
  title = NULL,
  text = NULL,
  background = NULL
)

Arguments

object: An scplot object (class scplot) returned from the scplot() function.
labels: A character vector. Replaces the automatically build labels. When a vector element is NA, the corresponding element will not be replaced (e.g. c(NA, "Variable 2", NA, "Variable 4")).
section_labels: A character vector of length two. The labels for the lines section and phase section.
case: Numerical vector with the case number or character string. case = "all" for all cases.
position: The position ("none", "left", "right", "bottom", "top", or two-element numeric vector)
datalines: If TRUE, a legend for the datalines is generated.
statlines: If TRUE, a legend for the statlines is generated.
phases: If TRUE, a legend for the phases is generated.
title: A list with text style parameters for the title.
text: List with text parameters ("family", "face", "colour", "size", "hjust", "vjust", "angle", "lineheight", "margin"). See element_text().
background: A list with background styling arguments (fill, color, size, linetype).
