In stratigraph: Toolkit for the plotting and analysis of stratigraphic and palaeontological data

Description

Plots a chart of proportional data (or another continuous variable) through time.

Usage

grid.prop.plot(x, y = NULL,
               increasing.down = FALSE)

Arguments

x	the matrix of data to be plotted as proportions; each column is a variable; each row is a time (or depth).
y	a vector with length equal to the number of rows in x; if NULL, it will be replaced by 1:nrow(x)
increasing.down	FALSE (default) plots times (depths) increasing up from the bottom to the top of the plot.
