joinStandData: compile stand data

Description

This function combines stand-level data for each plot, including cover by strata, plot slope, canopy cover, etc. Must run importData first.

Usage

joinStandData(
  park = "all",
  QAQC = FALSE,
  locType = c("VS", "all"),
  panels = 1:4,
  from = 2007,
  to = as.numeric(format(Sys.Date(), "%Y")),
  eventType = c("complete", "all"),
  output = "verbose",
  ...
)

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
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.
from	Year to start analysis, ranging from 2007 to current year
to	Year to stop analysis, ranging from 2007 to current year
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 (eg ACAD-029.2010). This feature is currently hard-coded in the function.
output	Allows you to return all columns or just the most important columns for analysis. Valid inputs are "short" and "verbose".
...	Other arguments passed to function.

Value

returns a dataframe with stand data attached to location and event data. Field names starting with "Pct" are midpoints between cover class ranges (e.g., 62.5 is the midpoint for 50-75

Examples

## Not run: 
importData()
# import 4 years of BOWA stand data
stand_df <- joinStandData(park = 'BOWA', from = 2015, to = 2019)

# import all visits, including QAQC, from 2019 in FRSP. Only return important data fields.
frsp_stand <- joinStandData(park = FRSP, from = 2019, to = 2019, QAQC = TRUE, output = 'short')

## End(Not run)
