Hello, I am trying to convert list of pairwise distances to a distance matrix for spatial analysis (kriging). For instance, I have something like this for each pair pf points, and I want to convert it to a matrix: point1 point2 distance 1 1 0 1 2 4 2 2 0 2 1 4 Please let me know if there is a function or method that can do this. Thanks, Christy [[alternative HTML version deleted]]

Hi there, I'd like to plot a triangle with each point having a certain color defined and fill it with the interpolated values. The following code shall represent somehow, three points with x,y, and the "amount" of red for example... point1 <- c(1.1, 1.7, 255) point2 <- c(2.2, 1.5, 180) point3 <- c(1.8, 2.2, 60) can anybody give me a hint which methods to use to realize it? Antje

Dear R, I have a bunch of geographic locations specified by lat-long coordinates. What's an easy way to calculate geographic distance between any two points? OR, perhaps there is a function for calculating a distance matrix for K sites? Sincerely, Scott Chamberlain [[alternative HTML version deleted]]

Dear R users, I want to generate two random variables (X1, X2) from uniform distribution (-0.5, 0.5) with a specified correlation coefficient r. Does anyone know how to do it in R? Many thanks! Menghui

Dear all, I'm generally not a big fan of GUIs, but I have just discovered one thing where a GUI would be a nice thing: creating color palettes. I'm creating an "image", for transparencies for a lecture I'm giving, so this is going to look great... :-) What I'm out for, is to make green tones and red tones, and a relatively sharp break between them. This break will

Hi all, Not completely sure what I''m doing, but I need to get data from another table based on and id. Below is some breakpointer output: irb> @params => {"project"=>{"project_description"=>"point2", "project_name"=>"break2"}, "action"=>"create_project", "id"=>{"collect"=>"6"}, "controller"=>"adm/project"} The one I want is the ''6'' in "id"=>{"col...
