Dear All, I am writing a project that will involve me writing code in R and php. i would appreciate if someone guide me on how to integrate R to php i wish to write an upload system in php that R will use and process and post back the result on php. thanks in advance ================ Worthy agent of Light ================ Jules Irenge MSc Student University of Liverpool [[alternative HTML

Hello everyone, I want to get a 1km by lkm grid raster image using my csv data. If I call latitude=a, longitude=b and preciptation=c. a<-(1,2,3,4,5) b<-(6,7,8,9,10) c<-(10,20, 30,40, 50) Then I found an example in r help which goes like pts = read.table("file.csv",......) library(sp) library(rgdal) proj4string(pts)=CRS("+init=epsg:4326") # set it to lat-long pts =

I am having trouble getting the rgal package to work on Mac OS X. I suspect it has something to do with the link between the rgal package and the associated programs GDAL and PROJ4. Here is the message I get when I attempt to load rgal > library("rgdal") Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object

Hi I'm trying to analyse some data and need to set the geographic coordinate system before I can do the analysis. I've been trying to use the project command in rgdal but keep getting an error message saying: Error in project(locationsMatrix, PROJECTION.OUT) : latitude or longitude exceeded limits ( PROJECTION.OUT <- "+proj=aea +lat_1=-18 +lat_2=-36 +lat_0=0 +lon_0=132

Hello, We (two mac users) have been attempting to install rgdal from "http://www.kyngchaos.com/software:frameworks", given that it is not available as a binary on the CRAN (binaries) of the "Package Installer". I have also tried to solve this problem by looking on the net for an old question, and though I have found it, the answers do not help very much because our porgraming

summary: I can display a lon-lat map on a lattice::layerplot, and I can display a Lambert conformal conic (LCC) map on a spam::image, but I can't display an LCC map on a lattice::layerplot. Example follows. What am I doing wrong? details: I've been using `lattice` (via `rasterVis`) successfully to display global atmospheric data, which works well enough (though I am definitely intrigued

Dear list, I have to compare two digital elevation models in raster format (geotiff). I then have to calculate the differences in altitude for each cell and make some statistics (basic as mean, median, std, range but also more "advanced" as RMSE) on that. I do not know very much how to proceed: 1) is it possible to import the geotiff in R? If so with which package? if not which is the

Hello I'm working with a large hydrological data set stored in a netCDF format. The file stores x and y coordinates in the UTM projected coordinate system, yet when I use image to graphically display the z variable, the image is distorted in the sense that it does not plot the map in the correct spatial organization. I'm wondering if I need to define the projection of the netCDF file

Hello R Community, I have imported a dataset which contain X Y coordinates and would like to recreate a shape file after some data analysis. What i have done is to import some taxlot data and join them based on some criteria. I want to check to see how well the joining went by reviewing the results in GIS. A couple things. I cant seem to import a shape file correctly using the maptools

Hi all, I am a begginer in R and I have been trying to use the Conditioned Latin Hypercube to choose sample points only in areas close to roads due to the difficult thorough access in the study area. I could use a code to create the points throughout the area, but I need to create a code to make the R only comes up with points close to this road. I've been using the packages

I have an XML file that has within it the coordinates of some polygons that I would like to extract and use in R. The polygons are nested rather deeply. For example, I found by trial and error that I can extract the coordinates of one of them using functions from the XML package: doc <- xmlInternalTreeParse('doc.kml') docroot <- xmlRoot(doc) pgon <-

Hello, I've been trying every now and then to find a cross operating system solution that would let me access PostgreSQL (and PostGIS) from R, or to access R from PostgreSQL. I know of pl/r, which accomplishes the latter, but has yet to be successfully ported to Windows. Similarly, I've tried to use Rdbi and DBI, but I haven't had luck with those on Windows either for connecting to

Hi, I am using in my workflow gIntersection from sp package.

After writing some code (stupidly without checking to see if there was code to do this already) to generate PostGIS SQL insert statements for simple geometry (wkt), I didn't check see if there is already something available to convert WKT strings into some R package geometry (sp?). Does anyone have any advice, hints, code (?) for converting the following OpenGIS strings into something

Hi there, there are many issues in wine and you can work around most of them somehow but there are few that you can not bypass. Copy Protection: wine seems to support a few copy protection systems, but not all. No of course you could say that a nocd crack should be used to work around that issue, but what if there is none available? Many games are done for different countries in different

Dear groups: I have tried to install rgdal in my Ubuntu, but it is not as straight as installing "sp". It demand the pre-installed GDAL and proj.4. I searched the source code in http://trac.osgeo.org/proj/ and http://trac.osgeo.org/gdal/wiki/DownloadSource. but don't know how to compile them. Who will give me a hint? Thanks a lot.

Is it possible to suppress compiling for the x64 arch when doing 'Rcmd build <mypkg>? Such that the pre-compiled package for binary distribution only contains a 'lib/i386/mypkg.dll'. For CHECK (and also INSTALL) there is a '--no-multiarch' argument, but I didn't find something similar for build. Otherwise, I suppose, I could - handle the problem in Makevars or
