prettyBars: prettyBars

In prettyGraphs: Publication-Quality Graphics

Description

prettyBars creates simple, crisp, publication-style quality bar graphs.

Usage

prettyBars(data, axis = 1, cex.names = 0.5, fg.col = NULL, axis.lims = NULL,
	show.bg.bars = FALSE, threshold.line = FALSE, main = "", bg.border = "white", 
	bg.col = NULL, bg.lims = NULL, sort.data = TRUE, horiz = TRUE, dev.new = TRUE)

Arguments

data	A set of data you would like to plot with bars for 1 dimension. Can be original data or factor scores or anything with at least 1 column.
axis	which axis (column of data) should be plotted?
cex.names	size of the text
fg.col	a matrix (single column) of colors for bars corresponding to rows of data.
axis.lims	two values in the form of c(min,max) for plot limits. If NULL, the min and max are computed.
show.bg.bars	a set of bars to be plotted under the bars in data. Used for a fill effect.
threshold.line	boolean. If TRUE, a line perpendicular to the bars is plotted. The lines appear at bg.lims.
main	A title to be placed at the top of the graph.
bg.border	color for show.bg.bars borders (see border in barplot)
bg.col	a matrix (single column) of colors for background bars to be plotted under fg.col.
bg.lims	two values in the form of c(min,max) for where to plot background bars or threshold line.
sort.data	a boolean. Will sort the bars by descending values.
horiz	see horiz in barplot.
dev.new	boolean. If TRUE, dev.new is called internally to create new device. If FALSE, a device must already be open.

Value

bp.cols

locations of bars (as would be returned by barplot).

Examples

	##stolen from ?barplot
	#tN <- table(Ni <- stats::rpois(100, lambda = 5))
	#the.colors <- rainbow(length(tN))
	#dev.new()
	#r <- barplot(tN, col = the.colors)
	#prettyBars(as.matrix(tN),axis=1,fg.col=as.matrix(the.colors),horiz=FALSE,dev.new=TRUE)
