I am using package ks() to build 3D representations of bird territories and calculate territory volume from spatial data (simply x, y, and z coordinates). What I want to do is determine at what sample size (# locations collected) does the territory volume stop increasing. This should give me an idea of the number of points needed for future seasons. So I have a couple of birds each with 200

I'm trying to figure out how to repeat a series of commands in R and have the outputs added to a dataframe after each iteration. My code starts this way... a<-read.csv("File1.csv") b<-read.csv("File2.csv")

Hello, I am trying to do something and I''ve been reading my Agile Web Development with Rails book and doing internet searches for several hours now and I have made no progress. Here''s the issue: I have a table of sales reps that is linked to a table of territories. There are around a thousand territories that are numbered and each sales reps has many territories. I will

Hello R users, I am trying to run a model with a binary response variable (nesting success: 0 failure, 1 success) and 8 fixed terms. Nesting success was examined in 72 cases in 34 territories (TER) during a 6 study years. Territories are nested within 14 patches (PATCH). I want to run a model taking into account these nested factors and repeated observation. To do this, I assume that the best

Hi, I posted this message earlier in "Rmetrics" and I don't know whether I posted in the wrong place, so I'm posting it again in Rhelp. I have a function in x and y and let's call it f(x,y). I need to get the Hessian matrix. i.e I need (d^2f/dx^2), (d^2f/dxdy), (d^2f/dydx), (d^2f/dy^2).I can get these using the D function. now I need to evaluste the hessian matrix for

I am a complete newbie in R . Using R 2.2.0 Windows XP This started as a simple exercise to see if I could produce a simple Cleveland style dotchart with a line from the '2' axis to the dot rather than a continuous line as do "dotchart" and "dotchart2". At least I could not find that option. I got a crude program to work but it includes unnecessary steps.

The NOAA National Centers for Coastal Ocean Science is hiring a Computational Ecologist, a statistical/computational ecologist with experience fitting advanced spatial models to marine wildlife survey data (e.g., seabirds and marine mammal transects, fisheries trawl surveys) in R and other statistical languages. This is a full-time, long-term stable contract position. We are looking for an

Dear list, i'm a new R user, so I apologize if the topic is already being addressed by some other user. I'm trying to determine if the reproductive success of a species of bird is related to a list of covariates. These are the covariates: ? elev: elevation of nest (meters) ? seadist: distance from the sea (meters) ? meanterranova: records of temperature ? minpengS1: records

I downloaded a US states+territories shapefile from http://www.weather.gov/geodata/catalog/national/html/us-state.htm and unzipped it into my working directory.

http://bugs.digium.com/bug_view_page.php?bug_id=0001429 * Support for other language syntaxes in saynumber Accidentally I opened this can of worms to see if we can add support for other language syntaxes for saying numbers. Seems like Swedish, english and norwegian follow the same syntax. I've integrated existing patches for french, danish and soon portuguese syntax. The steps we're

I have just started using ggplot2 and I seem to be doing something stupid in writing ggplot2 commands on more than one line. In the example below the commands on one line are working fine, but as soon as I put them on two lines I get an error. Can any one point out what I am doing wrong? It must be something blindingly simple. Thanks Example

Can anyone help me with this, which has been making me tear my hair out for 2 days now ? I have the following classes using has_many :through relationships... (I''ve changed the class names to make it easier to understand, so don''t beat me up about naming conventions ;) ) class Movie < ActiveRecord::Base has_many :localdetails has_many :territories, :through=>:rights

Friends, To update you on recent changes in svn trunk, I can inform you that we now have ever smarter ways to handle media streams in Asterisk than we do in 1.2 for the IAX2 and SIP protocols. * IAX2: Splitting signalling and media apart Starting with the IAX2 protocol, we now have the ability to transfer media streams to go directly between IAX2 servers and keep the signalling path.

Does anyone know an alternate way of calculating R2n with spatial data other than converting values into ltraj format (adehabitat package)? I have a series of geographic xy coordinates (in metres). I imagine I can subtract x1y1 from x2y2 to get the spatial difference (dxdy), but what function can I use to calculate R2n (i.e. net squared displacement) using this information? Tyler -- View

I have a data set (a) with 3 columns (X,Y,Z). The first 2 columns are numerical. The third column (Z) is a factor with three levels ("A","B","C"). What I want to do is turn each of the "A's" into different random numbers between 1 and 4, "B's" into a random number between 5 and 8, etc. I tried this:

Greetings, everyone. I've been trying to analyze bird nest survival data using generalized linear mixed models (because we documented several consecutive nesting attempts by the same individuals; i.e. repeated measures data) and have been unable to persuade the various GLMM models to work with my user-defined link function. Actually, glmmPQL seems to work, but as I want to evaluate a suite of

Last night, I upgraded one of my rails apps to 1.1. This app uses Markaby exclusively for its'' views, and once I checked out the latest revisiong of Markaby (r33), everything was working fine except for one thing: select_tag(''province_id'', options_from_collection_for_select(@provinces, "id", "name")) Now returns this (as you see it is spitting

Are there any plans to integrate Virtual Earth''s Bird''s Eye view to mapstraction? I tried an "integration hack" but then found out that there are too many issues involved (check whether birds eye is available for the current map area, disabling zoom controls,...). Has anyone else tried it? Franz
