plotFun.kde2d.hist: Plot a 2-dimensional kernel density plot and the histograms...

In anacv/plotFun: Helper functions for plotting data

Plot a 2-dimensional kernel density plot and the histograms of the two input variables.

Description

Plot a 2-dimensional kernel density plot and the histograms of the two input variables.

Usage

plotFun.kde2d.hist(var1, var2, xlim = range(var1, na.rm = T),
  ylim = range(var2, na.rm = T), breaks.den = NULL, title = NULL,
  cex.main = 1.5, xlab = NULL, ylab = NULL, n.bins = 25,
  add.contours = TRUE)

Arguments

var1	vector with data for one variable.
var2	vector with data for another variable.
xlim	2-element vector with X-axis limits for the density plot. Default: range of var1.
ylim	2-element vector with Y-axis limits for the density plot. Default: range of var2.
breaks.den	vector of breaks for the density plots. Example: breaks.den=seq(min, max, length=1000). By default, breaks.den is adjusted to the minimum and maximum kernel densities.
title	title above the plot.
cex.main	Relative size of the plot title. Default:1.5.
xlab	X-axis label.
ylab	Y-axis label.
n.bins	number of bins for kernel density calculation. Default= 25.
add.contours	logical. Add (default) or not contours for the kernel densities.

Details

The two-dimensional kernel density estimation is done with the function kde2d in package MASS.

Value

Plot with the 2-dimensional kernel densities and historgrams for the input variables.

## Not run: 
# Generate data
tas <- rnorm(1000, mean=15, sd=2)
td <- rnorm(1000, mean=8, sd=1)
# Plot 2-Dim Kernel density with histograms
plotFun.kde2d.hist(var1=td, var2=tas, xlab="Dew point temp.", ylab="Air temperature", 
n.bins=25, add.contours=FALSE, title="2D density plot", cex.main=2)
# add contours for the density values
plotFun.kde2d.hist(var1=td, var2=tas, xlab="Dew point temp.", ylab="Air temperature", 
n.bins=25, add.contours=TRUE, title="2D density plot with contours", cex.main=2)
