joinSoilSampleData: compile corrected soil sample data.

Description

This function verifies whether O and A horizons were named corrected based on the joinSoilLabData() function, then compiles average sample depth by horizon. Must run importData first. Only works for complete visits and plots that haven't been abandoned. Note that Earthworms are summarized in joinStandData(). Note that soils have only been collected once per plot from 2010 to 2014, and have not been sampled in ASIS or COLO.

Usage

joinSoilSampleData(
  park = "all",
  from = 2010,
  to = 2013,
  QAQC = FALSE,
  panels = 1:4,
  locType = c("VS", "all"),
  last_lab_year = 2014
)

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 "BOWA" Booker T. Washington NM 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 2010 to 2013.
to	Year to stop analysis, ranging from 2010 to 2013.
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
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.
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.
last_lab_year	The most recent year lab analyses have been completed for. This will allow non-lab QCed horizon data to be returned for years following. Otherwise, only QCed data horizon data are returned.

Value

returns a dataframe containing each plot and visit with soil sample data.Tot_Samp_cm is the total depth of O and A sampled. Litter is not included in total depth calculation. Note soil chemistry data are typically a year behind plot data, so corrected soil horizon depths will also be a year behind. Soil horizon data not yet QCed by lab data are indicated by the Lab_QC (T/F) column. Plots that weren't sampled during a given cycle are not returned. Horizon depths are averaged across samples of the same horizon type.

Examples

## Not run: 
importData() #default imports
# join horizon depth data for GETT
soil_GETT_O <- joinSoilSampleData(park = 'GETT', from = 2010, to = 2013)

## End(Not run)
