Description

Makes a spaghetti plot of tree-ring data.

Usage

spag.plot(rwl,zfac=1,...)

Arguments

rwl

a data.frame with series as columns and years as rows such as that produced by read.rwl.

zfac

a multiplier for rwl to enhance clarity when plotting.

...

arguments to be passed to lines.

Value

• None. This function is invoked for its side effect, which is to produce a plot.

This makes a simple plot of each series in a tree-ring dataset. Each series is centered first by subtracting the column mean using scale. The plot can be grossly tuned with zfac which is multiplier to rwl before plotting and centering.
