I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am no...

To represent a turtle inside a canvas (tcltk package), I have a serie of bitmaps representing the turtle heading in different directions and I would like to display the one that corresponds to the current direction of the turtle (function below). I have created with Paint a bitmap representing the turtle in BMP forma...

I would greatly appreciate some idea about the best approach to make a graphical interface of for a turtle world in R. In the turtle environment, the user controls movements of a turtle through the command line (e.g. forward(10), turn(5), etc.). The turtle should be displayed in the new position and heading after each command. Also, the turtle's path and, possibly, objects (squares, barriers, ...)...

Dear all, I am trying to do a "loose" implementation in R of the Turtle World (LOGO) and need some advices on graphical issues. In its current very simple implementation, the user can give order to the the turtle to move through the console. The current position and movements are displayed graphically (see below). In the future, I would like to permit the turtle to...

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$Clength) acts as a single predictor of ten multiple diet taxa abundances (prey.data) Neither rpart or mvpart seem to allow me to do multiple responses. (Or if they can, I'm not using the functions properly.) > library(rpart) > turtle.rtree<-rpart(prey.data~., data=turtle.data$C...

Dear R community, Is this sample size large enough to study differences between two groups of the populations? Q1: do the body temperatures differ between the two groups of the overwintering turtles juveniles and adults? One group (adults) has 6 turtles Second group (juveniles) has 1 turtle. There are 3 replications, i.e. the experiment was repeated over the three years, but using different turtles. We had about 130 observations (daily body temperature) per each turtle per year. I wo...

Hello, I've got a small dataset on box turtle shell measurements that I would like to perform a detrended correspondence analysis on. I thought that it would be interesting to examine the morphometrics for each species in the area of overlap and in areas where neither species occurs.  I've taken a look at the dune and dune.env datasets in...

Dear R community, I am wondering what experimental design I am dealing with? I study the effect of daily air temperature on daily body temperature of the overwintering turtles (i.e. sleeping in soil). The model is a cosine wave with the air temperature as a covariate. Objects are 19 overwintering turtles. Data were combined over the three years. Each turtle was studied only once during these years, while 2 turtles were studied during two years (see table below). The...

Hi R-listers, Q1) What is the difference between the scatterplot and plot function? Q2) I am able to make a graph with the scatterplot function: scatterplot(DevelopIndex ~ Veg, + data = Turtle, + xlab = "Vegetation border (m)", + ylab = "Embryonic development index") And have been successful. But I do not know if the lines are for: linear, non-linear, mean, upper and lower limits or percentile? This shows side boxplots and 4 lines. Yet this...

I did testing on generating this report from a 130 MB Quickbooks file. Locally, 15 seconds. Samba Server, 1:35. Shared off of my win98 Workstation, 2+ mins. I do not understand the reason it is SOO slow. I know it is a fairly large file. The only explanation I can come up with is the way QuickBooks is accessing the files. Maybe jumping all around the file, requiring many operations on the

...me stumped and I'm hoping someone here may be able to help. Recently I switched from a Gentoo Linux based OS to FreeNAS. The version of Samba running on FreeNAS is 3.5.5 (and was the same under Linux). I mainly use my FreeNAS/Samba box to share MP3 files to an Audiotron. One of the files is the Turtle Beach radio file, radio_tr.txt. When I was using Linux the Audiotron had no trouble reading and providing it the list of my favorite Internet radio stations. However under FreeNAS it is not read correctly. I think the Audiotron can see the file since it reports "no stations found" as thou...

Hi there guys... I've been watching the list for a while, had a quick question. I work for a company (Turtle Beach) that makes a product that takes MP3 files that reside on your PC or Network Attached Storage, and lets you play them anywhere else in your home. (From your stereo for example.) Anyway, we've added basic MP3 streaming support (and have now gone to external beta) that supports the Icecas...

I'm currently runing UW-IMAP (compiled vanilla) with procmail and mbox and am making my usual careful crawl (at turtle speed) through figuring out DC config. Some questions: a) I have something like 3-4 root imapd sessions so I presume that the default *login_processes_count* = 3 will be OK. I'm less clear about login_max_processes_count and login_max_connections = 256. A common enough heavy load has so...
