similar to: Adding a migration element to a deterministic spatial model

Hi all, I have a matrix simulating migration in a spatial model. I want to be able to define movement (the values of m1, m2 and m3) as only != 0 between adjacent patches and contingent on certain conditions as defined in the function. Here is the code: WET<-function(t) {everglades$precipitation[t]} #simply reads precipitation data from a csv, value is numeric AB<-function(WET,t)

Dear all, I'm aware if y has two separate functions (depending on the conditions of x) you can use the ifelse function to separate y into two separate functions depending on input. How do you do this if there a multiple different conditions for x? for example, y fits the following between t>0 & t<15----->function(t) t^2, y fits the following between t>15 &

Hi all, I am trying to import some functions into a script and am having difficulty in doing so. I am able to import a series of functions from a .tex file into my script, and call on each function by column name, however R reads them as data rather than as functions and I am struggling with the syntax to make R read them as a function instead. Below is a small set of the things I have tried:

Hi, I've encountered the following problem at a client. The problem results in one or more of the smbd processing continuously grabbing more and more memory until the system runs out of memory or just becomes unusable due to a low memory condition. This error is extremely serious as the entire server is eventually brought down by one error. After debugging this error at the

Hi all, I am attempting to use latin hypercube sampling to sample different variable functions in a series of simultaneous differential equations. There is very little code online about lhs or clhs, so from different other help threads I have seen, it seems I need to create a probability density function for each variable function, and then use latin hypercube sampling on this pdf. So far, I

Hello Everyone, My company is about to deploy * as replacement for our existing commercial Altigen PBX. Meanwhile, I've been trying to find the best cost effective SIP VoIP phone which we can use in office for 20-30 employees, as well as a few remote staff. Normally I wouldn't post about a VoIP phone, however, this phone was released less than a week so I thought I'd give some

Hi all, I'm having trouble locating a script that will allow to me to create graphs that show compound functions as a function of the simple function, rather than just x (or time as it is in my case). Currently I have the following functions defined in my script: > > > T1<-function(t) {27.5-12.5*cos(2*pi*t/365)**} > and > > B1<-function(T1,t)

hi I'm puzzled as to the relation between the REML score computed by gam and the formula (4) on p.4 here: http://opus.bath.ac.uk/22707/1/Wood_JRSSB_2011_73_1_3.pdf I'm ok with this for poisson, or for quasipoisson when phi=1. However, when phi differs from 1, I'm stuck. #simulate some data library(mgcv) set.seed(1) x1<-runif(500) x2<-rnorm(500)

Hi Greg, For quasi families I've used extended quasi-likelihood (see Mccullagh and Nelder, Generalized Linear Models 2nd ed, section 9.6) in place of the likelihood/quasi-likelihood in the expression for the (RE)ML score. I hadn't realised that this was possible before the paper was published. best, Simon ps. sorry for slow reply, the original message slipped through my filter for
