aorist.plot: Plots aorist output as a barplot.

In davidcorton/archSeries: Tools for Chronological Uncertainty in Archaeology

Description

Just a wrapper for barplot with some tweaks added, e.g. to make bars line up with data plotted by other archSeries functions.

Usage

aorist.plot(aorist, col = "grey", opacity = 255, lab.sp = 1,
  add = FALSE, ...)

Arguments

aorist	The output from an aorist call, or any data table with a character or factor column called 'bin' and a numeric column called aorist.
col	Character: colour of bars. Defined formally here rather than passed via ... simply so that it can be combined with 'opacity'.
opacity	Numeric: opacity of each line. Defaults to 80.
lab.sp	Integer: intervals at which to place bin labels. Defaults to 1, i.e. labelling every bin.
add	Logical: should data be added to current plot, or should axis.setup be called to start a new plot? Defaults to FALSE.
...	Other graphical arguments to be passed to barplot.

Value

None.

Examples

date.ranges <- data.table(Start=c(450, 450, 600), End=c(700, 800, 650), frag.count=c(3, 6, 25))
x <- aorist(date.ranges, weight=date.ranges$frag.count, 500, 1500, bin.width=50)
aorist.plot(x, col="grey60", ylab="Total probability density")
