sumSapDBHDist: sapling DBH distribution

Description

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

Usage

sumSapDBHDist(
  park = "all",
  from = 2007,
  to = as.numeric(format(Sys.Date(), "%Y")),
  QAQC = FALSE,
  locType = c("VS", "all"),
  panels = 1:4,
  speciesType = c("all", "native", "exotic", "invasive"),
  canopyForm = c("all", "canopy"),
  eventType = c("complete", "all"),
  units = c("density", "BA", "both")
)

Arguments

park	Combine data from all parks or one or more parks at a time. Valid inputs: "all" Includes all parks in the network "APCO" Appomattox Court House NHP only "ASIS" Assateague Island National Seashore "BOWA" Booker T. Washington NM only "COLO" Colonial NHP only "FRSP" Fredericksburg & Spotsylvania NMP only "GETT" Gettysburg NMP only "GEWA" George Washington Birthplace NM only "HOFU" Hopewell Furnace NHS only "PETE" Petersburg NBP only "RICH" Richmond NB only "SAHI" Sagamore Hill NHS only "THST" Thomas Stone NHS only "VAFO" Valley Forge NHP only
from	Year to start analysis, ranging from 2007 to current year
to	Year to stop analysis, ranging from 2007 to current year
QAQC	Allows you to remove or include QAQC events. FALSE Default. Only returns visits that are not QAQC visits TRUE Returns all visits, including QAQC visits
locType	Allows you to only include plots that are part of the GRTS sample design or include all plots, such as deer exclosures "VS" Only include plots that are part of the Vital Signs GRTS sample design "all" Include all plots, such as plots in deer exclosures or test plots.
panels	Allows you to select individual panels from 1 to 4. Default is all 4 panels (1:4). If more than one panel is selected, specify by c(1, 3), for example.
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 "invasive" Returns species on the Indicator Invasive List
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
eventType	Allows you to include only complete sampling events or all sampling events "complete" Default. Only include sampling events for a plot that are complete. "all Include all plot events with a record in tblCOMN.Event, including plots missing most of the data associated with that event. This feature is currently hard-coded in the function.
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 "both" Returns noth stem density and BA/ha.

Value

returns a dataframe with one row for each plot and either density, BA or both in 1cm size classes.

Examples

## Not run: 
importData()
sap_diam_dist <- sumSapDBHDist(park = 'RICH', speciesType = 'native', from = 2015, to = 2018, units = 'BA')

## End(Not run)
