LIMCaliforniaSediment: Linear inverse model specification for the Santa Monica Basin...

In LIM: Linear Inverse Model examples and solution methods

Description

Linear inverse model specification for the Santa Monica Basin (California) sediment food web as in Eldridge and Jackson (1993).

The Santa Monica Basin is a hypoxic-anoxic basin located near California.

The model contains both chemical and biological species.

The foodweb comprises 7 functional compartments and five external compartments, connected with 32 flows.

Units of the flows are mg /m2/day

The linear inverse model LIMCaliforniaSediment is generated from the file ‘CaliforniaSediment.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 LIMCaliforniaSediment

Usage

data(LIMCaliforniaSediment)

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")

Examples

CaliforniaSediment <- Flowmatrix(LIMCaliforniaSediment)
plotweb(CaliforniaSediment, main = "Santa Monica Basin Benthic web",
        sub = "mgN/m2/day", lab.size = 0.8)
## Not run: 
xr <- LIMCaliforniaSediment$NUnknowns
i1 <- 1:(xr/2)
i2 <- (xr/2+1):xr
Plotranges(LIMCaliforniaSediment, index = i1, lab.cex = 0.7,
        sub = "*=unbounded",
        main = "Santa Monica Basin Benthic web, Flowranges - part1")
Plotranges(LIMCaliforniaSediment, index = i2, lab.cex = 0.7,
        sub = "*=unbounded",
        main = "Santa Monica Basin Benthic web, Flowranges - part2")
## End(Not run)
