bird_focal.groups: Create a Focal Species Abundance Graph. Bar for each:...

In pointblue/RMN.functions:

Description

Takes bird data that has been prepared by bird_prepare function, to create a focal species abundance per year graph.

Usage

bird_focal.groups(df2, distance_focal,
  transect = c(levels(as.factor(df$Transect))),
  surveyyear = c(levels(as.factor(df$YEAR))))

Arguments

df2	A data frame object. Only will take bird_prepare(). See those functions for additional previous steps.
distance_focal	Filters the data by selecting only detections less than this value.
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 focal species abundance.

Examples

bird_focal.group(df2, transect="TOKA", surveyyear= 2016, distance_focal=300)
