nappCalc: Calculate net aboveground primary production

In troyhill/LUMCONplants: Allometry and Plant Dynamics in Louisiana Universities Marine Consortium Salt Marshes

Description

Calculate net aboveground primary production

Usage

nappCalc(dataset, liveCol = "above", deadCol = "above.dead",
  yearCol = "yr", siteCol = "site", timeCol = "monthYear",
  annualReset = TRUE, MilnerHughes = TRUE, EOS = FALSE,
  EOS_window = 1, summarize = TRUE)

Arguments

dataset	data
liveCol	name of column with live biomass data
deadCol	name of column with dead biomass data
yearCol	name of column with year data
siteCol	site/plot/experimental unit identifier
timeCol	column with timestamps (in form "mmm yyyy", e.g., "Jan 2015"). Can be character vector but to reduce opportunity for error use zoo:yearmon. This only matters for the summary statistics, which report peak timing.
annualReset	should data be reset to zero each year
MilnerHughes	if "TRUE", also implements Millner & Hughes 1968 (sum of positive changes in standing live biomass)
EOS	If "TRUE", end-of-season live biomass is reported. A column is appended showing live biomass in September (or closest month in dataset). If there was no sampling within some number of months (+- EOS_window) of September, value is reported as NA.
EOS_window	window used in EOSL detection.
summarize	If "TRUE", output will be a list with two elements: incremental data and summary data
