Plot a rank-abundance distribution

Take a vector of species [relative] abundances and plot a rank-abundance distribution or Whittaker plot.

radplot(
  ab,
  maxrich = length(comm),
  maxab = max(comm),
  fill = "red",
  shape = 16,
  size = 2.5,
  Whittaker = FALSE
)

Arguments

ab

A numeric vector of species abundances or relative abundances.

maxrich

Scalar, how many species to include space for

maxab

Scalar, how big is the largest abundance value

fill

Character string specifying a color, could be extended to permit name for community ID variable

shape

Character string for point shape, could be extended to permit name for community ID variable

size

Scalar, adjusts point size in ggplot object

Whittaker

Logical, if TRUE log-transform abundances

Value

ggplot object with a rank-abundance plot

Examples

radplot(c(20,8,5,4,2,1))

radplot(c(20,8,5,4,2,1), Whittaker = TRUE)
