Usage

sumQuadGuilds(
  speciesType = c("native", "exotic", "all"),
  park = "all",
  from = 2006,
  to = 2019,
  QAQC = FALSE,
  locType = "VS",
  output,
  ...
)

speciesType

Allows you to filter on native, exotic or include all species. "all" Returns all species. "native" Default. Returns native species only "exotic" Returns exotic species only

Examples

importData()

# compile exotic quad data for all parks and most recent survey.
exo_guilds <- sumQuadGuilds(speciesType = 'exotic', from = 2015, to = 2018)

# compile native quad data for more recent survey in COLO, with ferns and forbs split in separate guilds
COLO_guilds <- sumQuadGuilds(speciesType = 'native', from = 2015, to = 2018)
