plot.warn

Plot for posterior weaning parameters

Description

plot.warn is a plotting utile for quick visualization of the result of weaning age reconstruction from an object of class "warn". The measured and modeled bone collagen nitrogen isotope ratios (d15Ns) are plotted ageinst estimated ages.

Usage

## S3 method for class 'warn'
plot(x, hline.female = TRUE, hline.adult = FALSE, 
  adult.mean = NA, adult.sd = 0,
  is.legend = TRUE, is.female = TRUE, plot = TRUE, ...)

Arguments

`x`	an object of class `"warn"` generated by `warn`.
`hline.female, hline.adult`	logical; if `TRUE`, horizontal dotted lines indicating one standard deviation ranges of adult females and all adults are plotted on the figure; the default is `TRUE` for female and `FALSE` for adult.
`adult.mean`	the mean d15N of all adults, an optional single value.
`adult.sd`	the one standard deviation of all adult d15N, an optional single value. Utilized later in `plot.warn`.
`is.legend`	logical; if `TRUE` (the default), legend is plotted on the figure.
`is.female`	logical; if `TRUE` (the default), female mean d15N is plotted on the figure.
`plot`	logical; if `TRUE` (the default), a figure is plotted, otherwise a list of d15N changes in modeled bone and modeled diet is returned.
`...`	additional arguments passed to `plot`.

Details

The following three results on d15N are plotted against age, the original measured ratios of non-adult bone collagen (Measured d15N), modeled ratios of non-adult bone collagen (Modeled d15N), and modeled ratios of collagen synthesized entirely from consumed foods in the last half year (Modeld diet). These results are calculated in warn. Mean d15Ns of adult females and all adults can also be plotted.
