Description Usage Arguments Details Value See Also Examples

Classify the enzymes in their corresponding regulation group from the co-regulation matrix

1	class_group(beta_fun)

beta_fun

Matrix of co-regulation coefficients

Enzymes are classified in regulation groups depending on the co-regulation matrix. If the co-regulation coefficient is equal to zero between enzymes, the enzymes are in different regulation group, else there are in the same group.

Enzyme 1 is in the regulation group 1. Other enzymes are classified in ascending order.

Return a list classically named L_Phi of length p (the number of regulation groups). Each element q of L_Phi (the regulation group Φ_q) contains the numbers of co-regulated enzymes.

Function search_group to find the group of an enzyme.

#Only one group
beta <- matrix(c(1,10,5,0.1,1,0.5,0.2,2,1),nrow=3)
L_Phi <- class_group(beta)

#total number of regulation groups
p <- length(L_Phi) #gives 1


#Two groups
n <- 3
beta <- diag(1,n) 
beta[1,2] <- -0.32 
beta[2,1] <- 1/beta[1,2]

L_Phi <- class_group(beta)
p <- length(L_Phi) #gives 2
