kcone: Get the k-cone from a given flux cone.

In cdiener/dycone: dycone - analyze the dynamic landscape of metabolome data

Description

kcone() builds the k-cone from a given flux cone basis V and a set of metabolic terms M by calculating M^{-1}V.

Usage

kcone(V, mats, normalize = FALSE)

Arguments

V	The flux cone basis. Rows denote the dimensions and columns the individual basis vectors.
mats	The metabolic terms. A vector with as many entries as rows in V. All entries hsould be larger than 0.
normalize	Whether the basis vectors should be scaled to unit length. Not recommened for differential analysis.

Value

The obtained k-cone as a matrix.

See Also

polytope_basis for a way to calculate the flux cone, ma_terms to get mass action term.

Examples

data(eryth)
S <- matrix(c(1,0,0,1,-1,0, 0, -1), nrow=2)
rownames(S) <- c('A', 'B')
V <- polytope_basis(S)
K <- kcone(V, runif(ncol(S)))
