MQMF (version 0.1.1)

mm: mm calculates the predicted Michaelis-Menton length-at-age

Description

mm calculates length-at-age for the generalized Michaelis-Menton curve. The equation being (a x ages)/(b + ages^c).

Usage

mm(p, ages)

Arguments

p

is a vector the first three cells of which are a, b, c for the mm curve.

ages

is a vector of ages; could be a single number

Value

a vector of predicted lengths for a vector of ages in 'ages'

Examples

# NOT RUN {
 ages <- seq(0,20,1)    # sigma is ignored here
 pars <- c(a=23.0,b=1.0,c=1.0,sigma=1.0) # a, b, c, sigma
 plot1(ages,mm(pars,ages),xlab="Age",ylab="Length",lwd=2)
# }
