In QFASA: Quantitative Fatty Acid Signature Analysis

Description

Each prey fatty acid signature is systematically removed from the supplied prey database and its QFASA diet estimate is obtained by treating the individual as a predator.

Usage

prey.on.prey(preybase, dist.meas, gamma = 1)

Arguments

preybase	first column is name of species and remaining columns are fatty acids.
dist.meas	see help file for p.QFASA.
gamma	see help file for p.QFASA.

Value

diet estimate

Examples

data(preyFAs)
my.preybase <- preyFAs[, -c(1,3)]

# Note: uncomment examples to run. CRAN tests fail because execution time > 5 seconds
# diets.out <- prey.on.prey(my.preybase, 2)
# round(MEANmeth(diets.out), 3)
