In pointblue/RMN.functions:

Description Usage Arguments Value Examples

For the output of bird_wide.data(). This function subsets the wide dataframe by ranch, year and focal species.

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

`df`	is a dataframe. Only works with newpc2 created by add.zeros() and it's 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.
