Teasel {diagram} | R Documentation |
Transition matrix of the population dynamics model of teasel (Dipsacus sylvestris), a European perennial weed, as discussed in Caswell (2001), and in Soetaert and Herman, (in prep)
The life cycle of teasel can be described by six stages:
The matrix contains the transition probabilities from one compartment (column) to another (row)
Teasel
matrix with transition probabilities, where element ij denotes transition from compartment j to i
rownames and columnames are the component names
