sumSapDBHDist: sumSapDBHDist: calculates DBH distribution of saplings

In KateMMiller/forestMIDNarch: Package for importing, joining and querying MS Access based MIDN forest database tables.

Description

This function calculates DBH distribution by 1cm size classes. Must run importData first.

Usage

sumSapDBHDist(
  speciesType = c("all", "native", "exotic"),
  canopyForm = c("canopy", "all"),
  units = c("density", "ba"),
  park = "all",
  from = 2007,
  to = 2019,
  QAQC = FALSE,
  locType = "VS",
  panels = 1:4,
  output,
  ...
)

Arguments

speciesType	Allows you to filter on native, exotic or include all species. "all" Default. Returns all species. "native" Returns native species only "exotic" Returns exotic species only
canopyForm	Allows you to filter on canopy species only or include all species. "all" Returns all species, including low canopy species. "canopy" Default. Returns canopy-forming species only
units	Allows you to choose which metric to calculate: basal area or stem density "density" Default. Returns stems/ha "ba" Returns basal area in sq.m/ha

Value

returns a dataframe with one row for each plot and either density or BA

Examples

importData()
sap_diam_dist <- sumSapDBHDist(park = 'RICH', speciesType = 'native', from = 2015, to = 2018, units = 'ba')
