clogistic {primer} | R Documentation |
A function for continuous logistic growth, for use with ode
in the deSolve
package.
clogistic(times, y, parms)
times |
Times points that will return N |
y |
N |
parms |
a vector of logistic growth parameters |
The user does not put these directly into this function, but rather uses
ode
in the deSolve
package.
The function is based on the logistic growth equation
dN/dt = rN(1-alpha N)
or equivalently
dN/dt = rN(K-N)/K
Returns of list of one component (required by ode
).
