R Documentation

Simulate trophic discrimination factors

Description

This function returns trophic discrimination factors (TDF), given a number of observations, a mean and/or a standard deviation for deltaN and/or deltaC.

Usage

simulateTDF(
  nN = 56,
  meanN = NULL,
  sdN = 0.98,
  nC = 107,
  meanC = NULL,
  sdC = 1.3,
  seed = 3
)

Arguments

`nN`	number of observations for deltaN.
`meanN`	mean for deltaN.
`sdN`	standard deviation for deltaN.
`nC`	number of observations for deltaC.
`meanC`	mean for deltaC.
`sdC`	standard deviation for deltaC.
`seed`	numerical value to indicate reproducible results.

Value

a named list with TDF values for nitrogen and/or carbon

Examples

# 25 values of TDF for nitrogen, mean 3, sd, 1
simulateTDF(nN = 25, meanN = 3, sdN = 1)

# 18 values of TDF for carbon, mean 0.6, sd, 0.7
simulateTDF(nC = 18, meanC = 0.6, sdC = 0.7)
