dens2Dplot: Two dimensional density plot

In climatol: Climate Tools (Series Homogenization and Derived Products)

Two dimensional density plot

Description

This function generates a scatter plot enhancing density with different colors.

Usage

dens2Dplot(x, y, nbins=100, pal=NULL, xlab='', ylab='', xlim=c(NA,NA),
ylim=c(NA,NA), ...)

Arguments

x, y	Variables for the scatter plot.
nbins	Number of bins in X and Y coordinates of the scatter plot.
pal	Color palette
xlab, ylab	Labels for X and Y axis
xlim, ylim	Limits for X and Y axis
...	Other graphic parameters

Details

This function has been inspired by Elzizi's answer at http://stackoverflow.com/questions/18089752/r-generate-2d-histogram-from-raw-data The user can add a grid, title and other details to the scatter plot.

Examples

n=1000000; x=rnorm(n,15,4); y=x+rnorm(n,5,6)
dens2Dplot(x,y,xlab='Variable X',ylab='Variable Y',las=1)

## Let's add a grid and a title:
grid(col=grey(.4))
title('Example of dens2Dplot')
