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")
