centipede_plot
Description
Plot of species WA optima and tolerance
Usage
centipede_plot(x, spp, minN2 = 1, mult = 1)
Arguments
x |
A tolerance weighted weighted-average model from
|
spp |
data.frame of species data used to train the WA model |
minN2 |
numeric giving minimum N2 for inclusion in plot |
mult |
numeric multiplier for the tolerances |
Details
Extracts and sorts WA
optima and tolerances and
generates a ggplot.
Tends only to work well when there are a reasonable number of taxa,
otherwise it is difficult to read the names on the axis.
Rare taxa can be excluded with the minN2
argument.
The tol.cut
argument in WA
may need to be set to
prevent very small tolerances in rare taxa.
This function is very similar to the caterpillar
plot, but produces a ggplot
Value
A ggplot
object.
Examples
library(rioja)
data(SWAP)
mod <- WA(SWAP$spec, SWAP$pH, tolDW = TRUE)
coef(mod)
centipede_plot(mod, spp = SWAP$spec, minN2 = 20)
