LIMEverglades {LIM} | R Documentation |
Linear inverse model specification for the herpetological food web of the Everglades
Description
Linear inverse model specification for the herpetological wet prairie example from the everglades.
as described in Diffendorfer et al., 2001
The everglades are a freshwater wetland in Florida, USA.
The model contains 9 functional compartments and 3 external compartments, connected with 402 flows.
Units of the flows are gram wet weight / Ha / year
The linear inverse model LIMEverglades is generated from the file
Everglades.input which can be found in subdirectory /examples/FoodWeb
of the package directory
In this subdirectory you will find many foodweb example input files
These files can be read using Read
and their output
processed by Setup
which will produce a linear inverse
problem specification similar to LIMEverglades
Usage
data(LIMEverglades)
Format
a list of matrices, vectors, names and values that specify the linear inverse model problem.
see the return value of Setup
for more information about
this list
A more complete description of this structures is in vignette("LIM")
