bird_species.richness: Create a Species Richness per Point Graph

In pointblue/RMN.functions:

Description

Takes bird data that has been prepared by bird_prepare function and add.zero function to create a species richness per point graph based on ranch transect and surveyyear.

Usage

bird_species.richness(df, relative = T, distance = 300,
  transect = c(levels(as.factor(df$Transect))),
  surveyyear = c(levels(as.factor(df$YEAR))))

Arguments

df	A data frame object. Only will take newpc2 which is created by: add.zero() , bird_prepare(). See those functions for additional previous steps.
relative	if you want to have the graph consider effort.
distance	distance.
transect	A ranch code or a list of ranch codes ie."TOKA".
surveyyear	A year or multiple years. ie. c(2016,2018)

Value

A graph that summerises species richness of birds per point and year.

Examples

bird_species.richness(newpc2, "TOKA", 2016)
