barplot_s: Sorted Bar Plots

In sprof: Profiling, timing and optimisation utilities

Description

Creates a sorted bar plot with vertical or horizontal bars.

Usage

barplot_s(height, 
	horiz = FALSE,
	sort_by, 
	decreasing = TRUE, 
	lowtrim, hightrim, trimlegend = TRUE, 
	col, coli, colfun, 
	main, ...)

Arguments

height	either a vector or matrix of values describing the bars which make up the plot. See barplot.
horiz	boolean. Arrange bars horizontally.
sort_by	a variable to sort by. Defaults to height.
decreasing	boolean. Sorting direction.
lowtrim	A optional lower trim value. Observations with sort_by values up to lowtrim are discarded.
hightrim	A optional upper trim value. Observations with sort_by values from lowtrim are discarded.
trimlegend	Boolean. Show a legend about trimmed values.
col	a vector of colors for the bars or bar components. By default, grey is used if height is a vector, and a gamma-corrected grey palette if height is a matrix.
coli	An index into the col table, based on original sorting. If no index is given, the colour will be allocated after sorting.
colfun	A function or function name to generate a col palette. "grey" or "gray" is rescaled to 1..n.
main	overall title for the plot
...	Passed to barplot

Details

If no names are supplied, they are generated in the form x...

You man want to adjust the scale of the bar labels by using an additional argument such as cex.names =0.5.

More to come. Plots are among others from this collection:

Value

Invisible: A data frame with components

x	height
perm	the permutation applied
coli	the colour index applied
col	optional: the colours selected

Note

Part of this could go to the R base function barplot.
