bird_focal.graph: Create a Focal Species Abundance per Year Graph

In pointblue/RMN.functions:

Description

Takes bird data that has been prepared by bird_prepare function, add.zero function and bird_wide.data function to create a focal species per year graph based on ranch transect and focal group

Usage

bird_focal.graph(df, distance,
  transect = c(levels(as.factor(df$Transect))),
  surveyyear = c(levels(as.factor(df$YEAR))),
  choose_focal_group = c("Grassland", "Oak.Woodland", "Riparian"))

Arguments

df	A data frame object. Only will take wide.data which is created by: add.zero function , bird_wide.data(), bird_prepare(). See those functions for additional previous steps.
transect	A ranch code or a list of ranch codes ie."TOKA".
surveyyear	A year or multiple years. ie. c(2016,2018)
choose_focal_group	Three bird focal groups: Grassland, Oak Woodland, and Riparian. Each contain Spp codes that we consider focal species for that habitat type.

Value

A graph that summerises focal species abundance per year.

Examples

bird_focal.graph(wide.data, transect="TOKA", surveyyear= 2016, choose_focal_group="Grassland")
