simulateTEF: Simulate trophic enrichment factors

Description

This function returns trophic enrichment factors (TEF), given a number of observations, a mean and a standard deviation for deltaN and/or deltaC. This function has been replaced by simulateTDF, following the convention of naming trophic discrimination factors (TDF) instead of trophic enrichment factors (TEF).

Usage

simulateTEF(
  nN = 56,
  meanN = NULL,
  sdN = 0.98,
  nC = 107,
  meanC = NULL,
  sdC = 1.3
)

Value

a named list with TEF 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.

Examples

#simulateTEF() is deprecated, use simulateTDF() instead:

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

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