Xranges: Generates ranges of the unknowns of a linear inverse problem
In LIM: Linear Inverse Model examples and solution methods

Description Usage Arguments Value Author(s) See Also Examples

Given an inverse input list, generates the minimal and maximal values of the unknowns

1	Xranges (lim, ...)

`lim`	a list that contains the linear inverse model specification, as generated by function `setup.limfile`.
`...`	extra arguments passed to function `xranges` from package`limSolve`.

a 2-columned vector containing the minimum (column 1) and maximum (column 2) of each unknown.

Varranges which estimates the ranges of inverse variables

Plotranges to plot the ranges

function xranges from packagelimSolve

# ranges
xr   <- Xranges(LIMRigaAutumn)
xlim <- range(xr)

# parsimonious
pars <- Lsei(LIMRigaAutumn)$X

# plot
dotchart(x = pars, labels = rownames(xr), xlim = xlim,  
         main = "Riga Autumn ",
         sub = "ranges and parsimonious solution", pch = 16)
cc <- 1:nrow(xr)
segments(xr[ ,1], cc, xr[ ,2], cc)
