Hello again. Since my last post about giving up on Prey I have had to change my graphics card. The cooling fan on my ATI packed up and it was a choice of a new fan/heatsink combination and having to nearly rebuild my pc to allow room for it (nearly the size of my card and over 1 inch thick !) or replacing the card. Since I thought that the fan problem might be the thin end of the wedge and I might

Dear R-users, I am currently modifying a previously developed predator prey model and was curious if there was a way to add in a disturbance to the model (let's say at time t=100). The disturbance can be the introduction of 40 prey (N=40) and 10 predators (Pred = 10). I would like to see my model go from a state of equilibrium (up to t = 99), show this disturbance (at t = 100) and then

hi guys, plz help... i am trying to play American McGee's Alice(tm) (its from 2000), and i installed it. but when i try to run it i get: Code: American McGee's Alice win-x86 Nov 13 2000 ----- FS_Startup ----- Current search path: Z:\media\Windows\Games\Ububntu\Alice (2000)\base\pak4_english.pk3 (44 files) Z:\media\Windows\Games\Ububntu\Alice (2000)\base\pak3.pk3 (9 files)

Hi, WINE 1.2.2, Return to Castle Wolfenstein retail patched to 1.4.1, OS X 10.6.6, Mac Pro 2010 with ATI 5770. The error message is as stated in the title. According to a post here: > Newer AMD and NVIDIA drivers have so many OpenGL Extensions that Quake 3 engine based games crash when probing the extensions at game launch. > > 2 solutions: > > Download these fixed binaries

Hi all Just a quick thanks first for all the efforts that go into such a rewarding piece of kit. Well done Wine and all behind it. Now.....I'm not a big gamer, however, I wanted something different to civ4 and browsed your platinum games and found Call of Duty....next step Amazon.....2days later I try to play it. I have Ubuntu 8.10 and wine 1.1.10 The game installed but when I run it I

1) Testing of uidswap.c on a Tru64 UNIX V4.0G PK4 (BL22) machine shows the following defines to be required for correct uid changing semantics: #define BROKEN_SETREGID 1 #define BROKEN_SETREUID 1 #define SETEUID_BREAKS_SETUID 1 Failure to fix these contributes to breaking privilege separation (in a safe way: connections will fail while UsePrivilegeSeparation=yes, thanks to

Dear R-helpers ? I have 7 data points that I want to fit a continuous curve to, that should look similar to a sine wave My data points would mark the local minima and maxima respectively. This is what I?ve got so far. And I would keep doing so, but sadly nls() then says that it has reached the maximum number of Iterations? ?

Hi, I have data on stomach contents. Possible prey species are in the hundreds, so a list of prey codes has been in used in many labs doing this kind of work. When comes time to do analyses on these data one often wants to regroup prey in broader categories, especially for rare prey. In SAS you can nest a large number of "if-else", or do this more cleanly with "select"

This is my first post so greetings to everyone! Recently i wanted to play Jedi Academy, but unfortunately it was still asking for CD, despite i have mounted one. After patching it to 1.01 version and installing fixed binaries (from here: http://appdb.winehq.org/objectManager.php?sClass=version&iId=2315 ) it gived me this error: could not load OpenGL subsystem. Here's the error message:

Hi, I'm trying to move to R the last few data handling routines I was performing in SAS. I'm working on stomach content data. In the simplified example I provide below, there are variables describing the origin of each prey item (nbpc is a ship number, each ship may have been used on different trips, each trip has stations, and individual fish (tagno) can be caught at each

Hello, I have a syntactic problem with ode. How do I specify vectors of equations in ordinary differential equation systems. (i.e. in my case I want to simulate an a priory undefined number of species that have different parameters but the same behaviour) I demonstrate this using the Lotka Volterra example. The code below does not work and I have not a good idea how to specify this right. ##

Hi R experts :) I'm trying to carry out a survival model on my data, but I am unsure of whether it's appropriate or if I should do something specific in regards to hazard. My data is time to death by predator where I have 8 prey and one predator in the setting. This means that two prey can't possibly die at the same time and I can't quite get my head around how to include this in

Hi, I wonder if anyone can help me with specifying a right model for my analysis. I am a beginner to lme methods and though have spent already many hours studying from various books an on-line helps, I was unfortunately not able to find a solution to my problem on my own. Data structure: I studied escape behavior of three species of a prey to a predator. The prey specimens (many) were in a

Hi I am struggling with the correct code syntax to generate xyplots that are different from the default graphics option. This is simplified version of my data: site size dnaconc prey A 44 22.6 1 A 47 18.2 1 B 38 25.6 0 B 47 20.5 1 C 45 30.5 0 C 32 18.5 0 D 45 15.0 1 D 22 20.1 0 So I am using xyplot(dnaconc~size|site,data=bug,groups=prey) to generate 4 panels (one for each site). My

Dear R friends- I'm attempting to generate a regression tree with one gradient predictor and multiple responses, trying to test if change in size (turtle.data$Clength) acts as a single predictor of ten multiple diet taxa abundances (prey.data) Neither rpart or mvpart seem to allow me to do multiple responses. (Or if they can, I'm not using the functions properly.) > library(rpart)

Dear list, I´m using the mgcv package to model the proportion by weight of certain prey on the stomach content of a predator. This proportion is the ratio of two weights (prey weight over stomach weight), and ranges between 0 and 1. The variance is low when proportion is close to 0 and 1, and higher at intermediate values. It seems that the best way to go is to model this using the

Hello, I am trying to model a type II functional response of number of prey eaten (Ne) against number supplied (No) with a non-linear least squares regression (nls). I am using a modification of Holling's (1959) disc equation to account for non-replacement of prey; Ne=No{1-exp[a(bNe-T)]} where a is the attack rate, b is the handling time, and T is the experimental period. My script is as

*Thanks* all those who took the time to help me (even if the "question" was not related to - the use of - R). Now I think I can soundly make my point w/ the referee (can I use your replies? If so I intend to properly cite its use?!?). Regards, Eduardo Esteves ps - Sorry for not explaining the "biological details" of my posting: RNA/DNA is the ratio of RNA content to
