"rad"
for rank-abundance datanew("rad", ...)
, but
most often by a call to rad
or radpred
."data.frame "
, directly.
Class "list "
, by class "data.frame", distance 2.
Class "oldClass "
, by class "data.frame", distance 2.
Class "vector "
, by class "data.frame", distance 3.rad
to get an object of the class from a vector
of abundances; radpred
to get a rad-class
object of predicted abundances from a
theoretical distribution, qqrad
for quantile-quantile plots from a
rad-class
object, and pprad
for
percentile-percentile plots.## Creates a rad object from a vector of abundances
birds.rad <- rad(birds)
## Rank-abundance plot
plot(birds.rad)
## Same, with non-default graphical parameters
plot(birds.rad, pch=19, xlab="Abundance rank of species")
## Adding points from another data set
points(rad(okland), pch=19)
