Render a Pairs Plot as Fried Eggs and Beer

Description

Create a pairs plot where the lower left half comprises either fried egg contours or smoke ring contours, the upper right half comprises glasses of beer filled to the correlation point, and the diagonals show frequency histograms of the input data.

Usage

plotFriedEggs(A, eggs=TRUE, rings=TRUE, levs=c(0.01,0.1,0.5,0.75,0.95),
    pepper=200, replace=FALSE, jitt=c(1,1), bw=25, histclr=NULL) 

Arguments

A	data frame or matrix for use in a pairs plot.
eggs	logical: if TRUE, fry eggs in the lower panels.
rings	logical: if TRUE, blow smoke rings in the lower panels.
levs	explicit contour levels expressed as quantiles.
pepper	number of samples to draw from A to pepper the plots.
replace	logical: if TRUE, sample A with replacement.
jitt	argument factor used by function base::jitter when peppering. If user supplies two numbers, the first will jitter x, the second will jitter y.
bw	argument bandwidth used by function KernSmooth::bkde2D.
histclr	user-specified colour(s) for histogram bars along the diagonal.

Details

This function comes to us from Dr. Steve Martell of the Fisheries Science Centre at UBC. Obviously many hours of contemplation with his students at the local pub have contributed to this unique rendition of a pairs plot.

Note

If eggs=TRUE and rings=FALSE, fried eggs are served.
If eggs=FALSE and rings=TRUE, smoke rings are blown.
If eggs=TRUE and rings=TRUE, only fried eggs are served.
If eggs=FALSE and rings=FALSE, only pepper is sprinkled.
