optim.start: Start function (see demo)

In claus-e-andersen/clanOptim: R functions for non-linear fitting using the optim function from MASS

Description

Start function (see demo)

Usage

fix.parameters(c(10,30,40),list(p5=50, p2=20)) # gives 10 20 30 40 50
  fix.parameters(NULL,list(p1=20))        # gives 20
  fix.parameters(c(10,20),list(p3=30))    # gives 10 20 30
  fix.parameters(c(10,20),list(p5=30))    # error - there is no 5th parameter
  fix.parameters(c(10,20),list(p3=30,x3=45))  # error - cant refer to the 3rd parameter more than once

Arguments

df	is the dataframe with the data to which the model will be fitted
model	is the model equation
p.max	is the maximum of iterations
attach.df	controls if the dataframe will be attached or not
trace	controls if the function should be verbose during execution.

Value

A merged parameter vector
