Plot Kernel Density Estimates of Species Abundance Across a Focal Gradient
Description
This function plots each rescaled KDE fit to each specific-specific rise-and-fall in abundance across some ecological gradient variable.
Usage
plotGradientKDE(
speciesKDEs,
fullGradientRange,
xlim = NULL,
ylim = c(0, 1),
logY = FALSE
)
Arguments
speciesKDEs |
A list of rescaled-KDE data, where each element is a
different species, such as that output by |
fullGradientRange |
The minimum and maximum value of the ecological
gradient variable at which ecological assemblage data was observed.
If |
xlim , ylim |
Vectors of two elements, defining the minimum and maximum
values for the horizontal (x) axis and vertical (y) axis, respectively.
The default for |
logY |
Should the vertical axis (the relative height of rescaled KDEs) be portrayed with logarithmic scaling? |
Details
In many ways, this is an attempt to create empirical versions of the the hypothetical figures portraying abundance response curves relative to an environmental gradient in Patzkowsky & Holland (2012).
The ecological gradient variable is often an environmental characteristic, such as depth, oxygenation, altitude, precipitation, but this is not necessarily so.
Value
Nothing is returned, just a plot is made.
