panels.diag: More univariate panel plots.

In SciViews: SciViews - Main package

Description

Several panel plots that can be used with pairs().

Usage

panel_boxplot(x, col = par("col"), box.col = "cornsilk", ...)

panel.boxplot(x, col = par("col"), box.col = "cornsilk", ...)

panel_density(x, adjust = 1, rug = TRUE, col = par("col"),
  lwd = par("lwd"), line.col = col, line.lwd = lwd, ...)

panel.density(x, adjust = 1, rug = TRUE, col = par("col"),
  lwd = par("lwd"), line.col = col, line.lwd = lwd, ...)

panel_hist(x, breaks = "Sturges", hist.col = "cornsilk",
  hist.border = NULL, hist.density = NULL, hist.angle = 45, ...)

panel.hist(x, breaks = "Sturges", hist.col = "cornsilk",
  hist.border = NULL, hist.density = NULL, hist.angle = 45, ...)

panel_qqnorm(x, pch = par("pch"), col = par("col"), bg = par("bg"),
  cex = par("cex"), lwd = par("lwd"), qq.pch = pch, qq.col = col,
  qq.bg = bg, qq.cex = cex, qqline.col = qq.col, qqline.lwd = lwd, ...)

panel.qqnorm(x, pch = par("pch"), col = par("col"), bg = par("bg"),
  cex = par("cex"), lwd = par("lwd"), qq.pch = pch, qq.col = col,
  qq.bg = bg, qq.cex = cex, qqline.col = qq.col, qqline.lwd = lwd, ...)

Arguments

x	A numeric vector.
col	The color of the points.
box.col	The filling color of the boxplots.
...	Further arguments to plot functions, or functions that construct items, like density(), depending on the context.
adjust	The bandwidth adjustment factor, see density().
rug	Do we add a rug representation (1-d plot) of the points too?
lwd	The line width.
line.col	The color of the line.
line.lwd	The width of the line.
breaks	The number of breaks, the name of a break algorithm, a vector of breakpoints, or any other acceptable value for breaks = argument of hist().
hist.col	The filling color for the histograms.
hist.border	The border color for the histograms.
hist.density	The density for filling lines in the histograms.
hist.angle	The angle for filling lines in the histograms.
pch	The symbol used for the points.
bg	The background color for symbol used for the points.
cex	The expansion factor used for the points.
qq.pch	The symbol used to plot points in the QQ-plots.
qq.col	The color of the symbol used to plot points in the QQ-plots.
qq.bg	The background color of the symbol used to plot points in the QQ-plots.
qq.cex	The expansion factor for points in the QQ-plots.
qqline.col	The color for the QQ-plot lines.
qqline.lwd	The width for the QQ-plot lines.

Details

Panel functions panel_boxplot(), panel_density(), panel_hist() and panel_qqnorm() should be used only to plot univariate data on the diagonals of pair plots (or scatterplot matrix).

Value

These functions return nothing and are used for their side effect of plotting in panels of composite plots.

Author(s)

Philippe Grosjean [e-mail], but code inspired from spm() in package car.

Examples

# Example of scatterplot matrices with custom plots on the diagonal
# Boxplots
pairs(trees, panel = panel_smooth, diag.panel = panel_boxplot)
pairs(trees, diag.panel = panel_boxplot, box.col = "gray")
# Densities
pairs(trees, panel = panel_smooth, diag.panel = panel_density)
pairs(trees, diag.panel = panel_density, line.col = "red", adjust = 0.5)
# Histograms
pairs(trees, panel = panel_smooth, diag.panel = panel_hist)
pairs(trees, diag.panel = panel_hist, hist.col = "gray", breaks = "Scott")
# QQ-plots against Normal theoretical distribution
pairs(trees, panel = panel_smooth, diag.panel = panel_qqnorm)
pairs(trees, diag.panel = panel_qqnorm, qqline.col = 2, qq.cex = .5, qq.pch = 3)
