Hello- I am using the vegan package PCMN() because I need to use option of row weights (I am using CCA following the selection of the significant/positive PCNM variables). In the library PCNM (PCNM function), the Moran's I is calculated for you as part of the function. I see that I need to calculate Moran's I separately in order to retain the eigenfunctions with positive spatial

Background: OS: Linux Ubuntu Dapper R : Version 2.3.1 (2006-06-01) Emacs 21.4.1 ESS Colleagues This is neither a bug report, nor a complaint, so I think this is the appropriate list. I am getting an odd font problem with a pdf generated using pdf(file = "../figures/PCNM.models.larvae.fluor.zoo.stability.2001.and.2002.pdf", title="", family="serif",

The Gluster Community would like to congratulate the OpenStack Foundation and developers on the Havana release. With performance-boosting enhancements for OpenStack Block Storage (Cinder), Compute (Nova) and Image Service (Glance), as well as a native template language for OpenStack Orchestration (Heat), the OpenStack Havana release points the way to continued momentum for the OpenStack community.

Hi all, I am fairly new to R and I am trying to run mvpart and create a MRT using explanatory variables and covariables. I've been following the procedures in Numerical Ecoogy with R. The command (no covariables) which works fine - ABUNDTMRT <- mvpart(abundance ~ .,factors,margin=0.08,cp=0,xv="1se",xval=nrow(abundance),xvmult=100,which=4) where abundance is 4th root

Dear R-helpers, I have a time series analysis problem in R: I want to analyse the output of my simulation model which is proportional cover of shrubs in a savanna plot for each of 500 successive years. I have run the model (which includes stochasticity, especially in the initial conditions) 17 times generating 17 time series of shrub cover. I am interested in a possible periodicity of shrub

Dear R-Experts, Dear friends of dung. I have a statistical Problem, to which nobody I asked could give me an answer. Maybe you can. I was in the African-Savanna and made a Dung-Monitoring. This means I walked randomly over the field and for every Dung-Event I found I noted following parameters: Species (Waterbuck, Giraffe, Reedbuck); Age-Category (less than a week, more than a week & less

Hello everybody, I Would like to get some help to plot together, Principal Components Analysis (PCA) and clusters. I am handling environmental data from 25 locations spread across 5 different ecosystems.When grouped into 5 clusters, locations from different ecosystems are arranged in the same group. So, I want to plot together PCA and Clusters, in a such way that locations belonging to the same

Dear All, I hope the title speaks by itself. I believe that there should be a solution when I see what Mclust is able to do. However, this problem is quite particular in that d3 is not known and does not necessarily correspond to a common distribution (e.g. normal, exponential ...). However it must look like dmix and d1 to some extent. To illustrate my problem I worked out a simple example:

Imagine that I have a large number of points (given by coordinates x and y) that vary in density per space. For the purpose of demonstration it could be generated like this: s <- data.frame(x=runif(10000,0,900),y=runif(10000,0,900)); plot(s) I want to create polygons around the points where point density is greater than a selected threshold (for example, by using krieging or equivalent

Hello, I need to calculate the centroids of some spatial polygons that I have placed into a Polygons-class object. Is the labeling point in the Polygons-class the centroid of the polygon? Thank you for your help.

I am using wireframe from the lattice package, with the shade option set to TRUE. When I output to PDF or Postscript, a line gets drawn around each polygon of my surface which causes ugly Moir? effects and doesn't make sense in my application (think the plot of Maunga Whau--gridlines don't make sense). This does not happen when I display on the screen-- then I just get the surface as

Dear R users, I would like to know how to indentify the polygons that are located on the border of a map (i.e.shapefile). Do you have any suggestion on how to do it? Thank you very much, Leo Monasterio. [[alternative HTML version deleted]]

I have a SpatialPolygonsDataFrame object (sp package). It contains 40 polygons. Now I want to join some of the polygones. I cannot figure out how to do that? Any ideas? The code below produces a map of Germany and I need to join some counties. library(sp) library(RColorBrewer) # get spatial data for Germany on county level con <- url("http://gadm.org/data/rda/DEU_adm3.RData")

Hi. For a spatial analysis (its visualization) I need to produce a map of conditions and traits. When I used SpatialPixelsDataFrame (sp package) my grid cells were regular and between each row was a small gap, which is not only messy but incorrect. So I generated the coords of each grid from the centroids in order to elongate the cells manually (or does anybody know another way to solve this?).

i saw many people can't get Kotor running well its not Kotor its your drivers...

Hello. I'd like to convert voronois object created by tripack to polygons to use them in GIS(Geographic Information Systems) software. I tried to create voronoi objects by using following code. > library(tripack) > x <- rnorm(10) > y <- rnorm(10) > plot(x,y) > v<-voronoi.mosaic(x,y) > plot(v) But from here, I could not create polygons. Of course, I know

Dear all, How to generate one outline polygon for each point clump? Are there any present functions in ArcView, ArcGIS, R or some freewares? I just had a quick look at the package adehabitat and did not find the function. To my knowledge, I could do it as follows: 1) make a grid map of my study area with cell values = 0; 2) assign 1 to the cells containing at least one point; 3) convert the

I'm sure this has been asked before quite a few years ago and in great quantity, but I've been searching threads on various sites for a few hours now, and can't seem to find a fix. Anywho, I have KOTOR installed, and it runs in fullscreen and all that, however, all my polygons are white, as in, there is no textures. All the text within the game is also just blue boxes. This obviously

Hi This is for developers of extension packages that provide extra *graphics devices* for R. In the *development* version of R, support has been added to the graphics engine for rendering polygons with holes (e.g., maps with lakes with islands ...). The API change is a new dev_Path() function for graphics devices. The R_GE_version constant (in GraphicsEngine.h) has been bumped up to 8 as a
