This function randomly samples routes from within a stage.

sample_dove_routes(dat, years = c(1990, 2000, 2005), max.sample = 50)

Arguments

dat	Dataframe containing BBS data. Must contain columns for Year, Aou species code and Route
years	Years for for which you want to generate data for

Examples


## create data
#dat <- sample_dove_routes(dat = doves_PA,
 #       years = c(2005,2007,2010))

## Make year a factor
#dat$Year <- factor(dat$Year)

## Plot means with 95% confidence intervals

library(ggplot2)
library(ggpubr)

#ggerrorplot(dat,
 # x = "Year",
  #y = "tot.seen",
  #desc_stat = "mean_ci",
  #add = "mean")
