Qindex_graphics: Visualize Qindex object using R package 'graphics'

In Qindex: Continuous and Dichotomized Index Predictors Based on Distribution Quantiles

Visualize Qindex object using R package graphics

Description

Create perspective and contour plots of FR-index integrand using R package graphics.

End users are encouraged to use function integrandSurface with plotly work horse.

Usage

## S3 method for class 'Qindex'
persp(
  x,
  n = 31L,
  xlab = "Percentages",
  ylab = "Quantiles",
  zlab = "Integrand of FR-index",
  ...
)

## S3 method for class 'Qindex'
contour(
  x,
  n = 501L,
  image_col = topo.colors(20L),
  xlab = "Percentages",
  ylab = "Quantiles",
  ...
)

Arguments

x	Qindex object
n	integer scalar, fineness of visualization, default 501L. See parameter n.grid of function vis.gam.
xlab, ylab	character scalars
zlab	character scalar, for function persp.Qindex
...	..
image_col	argument col of image.default

Value

Function persp.Qindex, a method dispatch of S3 generic persp, does not have a return value.

Function contour.Qindex, a method dispatch of S3 generic contour, does not have a return value
