Memory leak in R v1.5.1?
Try:
silly.fn <- function(x) { (x[1]-5)^2 + (x[2]-2)^2 }
optim( par=c(3,1) , silly.fn )
you'll get the correct answer. Ravi. ----- Original Message ----- From: Adaikalavan Ramasamy <ramasamy at stats.ox.ac.uk> Date: Tuesday, August 6, 2002 12:25 pm Subject: Re: [R] Memory leak in R v1.5.1?
Hi ! I am trying to minimise a function over 2 variables
simultaneously. Is
this possible ? I have only recently been introduced to optim() and
optimise() function. Here is simple example of what I tried to do :
silly.fn <- function(x,y) { (x-5)^2 + (y-2)^2 }
optim( par=c(3,1) , silly.fn )
Analytically, the answer should be (5,2) but the computer is
asking for the
y value. Is there a function to do the minimisation simultaneously
in S-PLUS
or R ?
Many thanks, Adai.
