includeLegend: Include Legend

Description

Include legend in regression plot (function plot()) or in bias plot (function plotBias ()) with two or more lines.

Usage

includeLegend(
  models = list(),
  digits = 2,
  design = paste(1:2),
  place = c("topleft", "topright", "bottomleft", "bottomright"),
  colors,
  lty = rep(1, length(models)),
  lwd = rep(2, length(models)),
  box.lty = "blank",
  cex = 0.8,
  bg = "white",
  inset = c(0.01, 0.01),
  bias = FALSE,
  model.names = NULL,
  ...
)

Value

Legend in plot.

Arguments

models

list of length n with Objects of class "MCResult".

digits

number of digits in Coefficients.

design

type of legend design. There are two possible designs: "1" and "2" (See example).

place

place for Legend: "topleft","topright","bottomleft" or "bottomright".

colors

vector of length n with color of regression lines.

lty

vector of length n with type of regression lines.

lwd

vector of length n with thickness of regression lines.

box.lty

box line-type

cex

numeric value representing the plotting symbol magnification factor

bg

the background-color of the legend box

inset

inset distance(s) from the margins as a fraction of the plot region when legend is placed by keyword.

bias

logical value. If bias = TRUE, it will be drawn a legend for plotBias() function.

model.names

legend names for different models. If NULL the regression type will be used.

...

other parameters of function legend().
