Web16 de nov. de 2004 · The zero-growth isocline describes expected equilibrium population sizes of one species if abundance of the second species is held constant, and vice versa. The relationship between the two species is assumed to be linear, i.e., the isoclines for species 1 and species 2 can be written as equations for a straight line (y = a + bx). Web15 de dic. de 2024 · R plot isoclines for a given value (z), where x*y=z. I am attempting to plot a line that includes all of the products of x and y that equal a given value ( z ). Right now I can make a matrix of all the x and y pairings and then hopefully get enough entries within group_id to be able to plot the line. This is not elegant and is more approximate ...
