TEF | R Documentation |
This function returns trophic enrichment factors (TEF), given an author, element and a type. For convenience 'type' includes a number of categories depending on the author. At the moment it includes TEF data from Post (2002) and from McCutchan et al (2003). This function is maintained for compatibility backwards of version 0.6.8.
TEF(author = "Post", element = "both", type = "all", seed = 3)
author |
could be either "Post" or "McCutchan" at the moment. |
element |
can be "both", "N" or "C" |
type |
this argument only works for "McCutchan" author (their Table 3). "all" returns all TEF data; "whole" and "muscle" returns TEF separated per type analysis; "acidified" and "unacidified" returns TEF separated per acidification; and "Rainbow Trout" and "Brook Trout" returns TEF separated per fish species (according to their Table 1). |
seed |
integer to have replicated results |
a list (if element = "both") or a vector (if element ="N" or element = "C") containing TDF values
# TEF() is deprecated, use TDF() instead: TDF(author = "McCutchan", element = "N")
