soil.spec (version 2.1.4)

spec.env: Soil.spec package specific environmental variables

Description

Generates internal environment / package specific parameters and settings that can be later on passed to other functions.

Usage

spec.env(MIR = c(390, 7500), NIRS = c(3900, 12500),  NIRP = c(4000,10000), VISNIR1 = c(420, 960),  VISNIR2 = c(1020, 1770),  VISNIR3 = c(1830, 2480), icraf.htsxt = c(3578, 7497.964, 599.76),  icraf.alpha = c(2542, 3998.12872, 399.387991),  icraf.mpa = c(2307, 12493.2, 3598.69),   CO2.band = c(2350.8,2379.8), signif.digit = 5,  attributes = c("ORCCNS", "PHIHOX", "ALUM3S",  "ECAM3S", "EXKM3S", "EMGM3S", "ENAM3S", "EXB",  "NITCNS", "SNDLDF"),  mdnames = c("MID", "Instrument_name", "Instrument_URL",  "Laboratory_name", "Laboratory_contact", "Laboratory_URL", "Material_class", "Wavenumber_conversion", "Wavenlength_unit", "Location_error"), show.env = FALSE)
