Plots: Barcharts, Roseplots, and Area Adjusted Roseplots via ggplot2

Description

A suite of functions to demonstrate why the area in roseplots need adjusting

Usage

  barchart(data = d, pos = p, width = 0.8, alpha = 0.6,
    border.col = "black", rad.max = NULL)

  roseplot(data = d, pos = p, width = 0.8, alpha = 0.6,
    border.col = "black", rad.max = NULL, start = pi/3)

  aaroseplot(data = d, pos = p, width = 0.8, alpha = 0.6,
    border.col = "black", rad.max = NULL, start = pi/3)

Arguments

data	A dataframe that is three columns wide and has the column names "prob", "cond", and "region": "prob" is the probability of being in the "region" and "cond" is a condition or grouping variable. See prob.cond.region in the examples.
pos	passed to geom_bar() as the "position" value: currently supported are "dodge" and "stack"; "super" superimposes layers up to 10 levels of "cond". If pos="super" throws the error "Error in if (nrow(layer_data) == 0) return() : argument is of length zero" then exit out, restart R, and library(devtools); install_github("ggplot2","hadley"). See https://github.com/hadley/ggplot2/issues/587 for details
width	passed to geom_bar() as the "width" value: determines the spacing between bars/clusters of bars between the regions. Default is 0.80
alpha	Passed to geom_bar() as the "alpha" value – default is 0.6; 1 is opaque and 0 is transparent
border.col	Passed to geom_bar() as the "color" value – "black" is default and NA is transparent for border color control
rad.max	[0, 1.05*rad.max] is the range of the radius-scale. rad.max should be specified as a number between 0 and 1. Default is NULL, which means ggplot will handle the range display automatically/default.
start	Passed to coord_polar() as the "start" value – default pi/3 rotates the circle so that the East (EE) label meets the right side of the page (not applicable to barchart())

Examples

data(prob.cond.region)
## Dodged barchart, roseplot, area adjusted roseplot
be <-   barchart(prob.cond.region, "dodge", rad.max=0.5) + ggtitle("Barchart (dodge)")
re <-   roseplot(prob.cond.region, "dodge", rad.max=0.5) + ggtitle("Roseplot (dodge)")               + scale_fill_discrete(guide=FALSE)
ae <- aaroseplot(prob.cond.region, "dodge", rad.max=0.5) + ggtitle("Area Adjusted Roseplot (dodge)") + scale_fill_discrete(guide=FALSE)
multiplot(be,re,ae, cols=2, rows=2)
## Stacked barchart, roseplot, area adjusted roseplot
bk <-   barchart(prob.cond.region, "stack", rad.max=0.5) + ggtitle("Barchart (stack)")
rk <-   roseplot(prob.cond.region, "stack", rad.max=0.5) + ggtitle("Roseplot (stack)")               + scale_fill_discrete(guide=FALSE)
ak <- aaroseplot(prob.cond.region, "stack", rad.max=0.5) + ggtitle("Area Adjusted Roseplot (stack)") + scale_fill_discrete(guide=FALSE)
multiplot(bk,rk,ak, cols=2, rows=2)
## Superimposed barchart, roseplot, area adjusted roseplot
br <-   barchart(prob.cond.region, "super", rad.max=0.5) + ggtitle("Barchart (super)")
rr <-   roseplot(prob.cond.region, "super", rad.max=0.5) + ggtitle("Roseplot (super)")               + scale_fill_discrete(guide=FALSE)
ar <- aaroseplot(prob.cond.region, "super", rad.max=0.5) + ggtitle("Area Adjusted Roseplot (super)") + scale_fill_discrete(guide=FALSE)
multiplot(br,rr,ar, cols=2, rows=2)
## Dodged, Stacked, and Superimposed barchart, roseplot, area adjusted roseplot in same plot
## tip:  maximize window after render
multiplot(be,bk,br,re,rk,rr,ae,ak,ar, cols=3)
