simulateTDF: 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
)

Value

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

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.

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)
