Hello I wonder if anybody can help, I am using the package adehabitatHR to estimate the potential distribution of a species using the command "domain" In the example given in the AdehabitatHS manual a map containing elevation information is loaded (class= spatial pixels data frame) as well as the GPS points of the animals being tracked, these are then plotted on each other and

My sincerest apologies, as this is a very elementary problem, but I have searched through archives and FAQs and on the web, and I am at the end of my own resources. I need to do analysis of a spatial point process occuring with four counties, using spatstat. I've had no trouble importing the shapefiles, but I can't seem to figure out what I need to do in order to use the boundary as an

Hello I'm working with NetCDF files in an animation and am trying to superimpose a shapefile on the image as it is generates the html pages. If I take out the lines for the shapefile, it works correctly, however I'm having difficultly including the shapefile. If anyone has any ideas I would greatly appreciate the assistance. R Version 2.15.0 (2012-03-30) Platform i386-pc-mingw32/i386

I figured it out, at least enough to get rgeos's gSimplify function to work, which was my original goal; the stringr problem was with 0.2, however I got stringr 0.5 to install by changing the minimum version in DESCRIPTION from R2.11 to R 2.10. ... Thanks for the help! ############# # This is how I got rgeos to install in R GUI on my Intel Mac OS X 10.4: ############# # stringr

Hi, I have done the interpolation for my data and I was able to create the contours in multipanel with the help of Pascal. Now, I want to clip the contour with the shapefile. I want only the portion of contour to be displayed which falls inside the boundary of the shapefile. The data mydata.csv can be found on https://www.dropbox.com/s/khi7nv0160hi68p/mydata.csv The data for shapefile can be

I would like to create a voronoi map that can show me point values like the ones in colum street_cle. I was able to do it in tileplot(latticeExtra) like the ones attached, and with the following commands: xy=list(x=x2$X, y=x2$Y) xy$street_cle <- x2$street_cle tileplot(street_cle~ x*y, xy) But this is a trellis. Is it possible to be converted to a shapefile or image so I can plot it using

Dear all, I am currently working with the spatstat package, using windows and pixel images. First: My aim is to transform a shapefile (see attached) into a pixel image. My idea is to start transforming the shapefile into a Spatial Polygon file: x <- readShapeSpatial("200001441.shp") y <- as(x, "SpatialPolygons") z <- as.owin(y) Given z, I want to identify each

Dear R help list, ? I am working on some data from a study on the habitat use and movement patterns of fish using a marine protected area in Hawaii.? We have a number of acoustic receivers in a MPA, and any time a tagged fish passes within range it records the date and time of detection.? I am trying to make bubble plots?showing the number of detections for each fish at each receiver.? I have been

I'm not sure if this is what you want. But the function coordinates() in sp package gives you the coordinates of SpatialObjects. Regards.

Hopefully the attachment will make it this time... Hi: I am practicing with the attached shapefile and was wondering if I can get some help. Haven't used 'rgdal' and 'maptools' much but it appears to be a great way bring map data into R. Please take a look at the comments and let me know if I need to explain better what I am trying to accomplish. library(rgdal)

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]]

Hi, I am working on a library of map functions for R and I have started with code to read shapefiles (the format is not great but it is ubiquitous). I am not a windows person, but where I am working I don't have access to any UNIX machines easily. So here's the problem I wrote C code to read the information out of the shapefile header and I compiled it using the script given in Ripley and

I'm new to R and I'm working on point shapefiles. Is there a way that you could interpolate a shapefile via kriging in R using an attribute? All examples on the internet are using txt files and CSVs. Thanks a lot. [[alternative HTML version deleted]]

I am trying to estimate home range size using the plug-in method with kernel density estimation in the kernel smoothing (ks) package. Unless there is another way I am not familiar with, in order to calculate spatial area under the space I need to convert my kde () object into a spatial object somehow in order to calculate its spatial area. Could someone demonstrate how this might be done? --

Hi all, who knows how to get an ESRI Shapefile for the NUTS-2 Regions of the enlarged European Union? Particularly I want to draw maps of Germany, Poland, Czech Republik, Hungary and Austria. I've found Shapefiles for the US, Russia and other countries elsewhere in the web, but for Europe it seems really difficult. With many thanks for any hint Albrecht

Hola buenos días: Hace algún tiempo mandé una duda que sobre fichero tipo shapefile que publica el Instituto Geográfico Nacional de España y que detallo en el word Duda_sobre_shp. El tema es que al final no obtuve respuesta (es cierto que lo mandé en Agosto y en esa fechas entiendo que sea normal, por tanto por recomendación de un conocido vuelvo de nuevo a remitir la cuestión) Como no podía
