Hello Everybody. i am installing rgeo in R-2.13 on debian lenny. i am getting following error. Can anybody help me why i m not able to compile rgeos. rgeos_misc.c: In function ‘rgeos_hausdorffdistance’: rgeos_misc.c:55: error: ‘GEOSHausdorffDistance_r’ undeclared (first use in this function) rgeos_misc.c:55: error: (Each undeclared identifier is reported only once rgeos_misc.c:55: error: for

Dear R community, I'm trying to graphically illustrate my data with a worlmap. Unfortunately, my data is partly on country basis and partly on regional basis (e.g. certain African countries are aggregated to one region). I am using the package rwoldmap. The data on country basis can be mapped, but our defined regions cannot be identified in R. Therefore, all the countries in these

Fíjate, había visto aggregate del paquete raster, pero lo había excluído porque pensaba que trabajaba sólo con imágenes raster... ¡qué cosas! :) Gracias. Lo miraré.

Some notes on installing rgeos in R 2.14.0 on a Linux Mint 11 (x86_64-pc-linux-gnu) machine 1. rgeos 0.1-15 will not run with GEOS 3.2.0-1, which is the version currently available on Synaptic package manager 2. I installed GEOS 3.3.1 (the latest version) from http://trac.osgeo.org/geos/, but rgeos will not run with this either 3. I then install GEOS 3.2.3, and now rgeos works fine! It seems

¿Existe alguna función en el paquete "sp" para crear un mapa de comarcas a partir de uno municipal? El "shp" de los municipios lo tengo… necesito crear el "shape" comarcal… Lógicamente tengo un data.frame con la variable "comarca"… Normalmente en google suelo encontrar estas cosas, pero en este caso estoy inusualmente muy perdido… Gracias de antemano.

Hi I am seeking to understand why the methods package (to be specific `methods:::.findOrCopyClass` when called by `setIs` when called by `setClass`) emits a warning message such as ` class "SpatialLinesNULL" is defined (with package slot 'rgeos') but no metadata object found to revise subclass information---not exported? Making a copy in package 'minweSpatialNULL `

Dear list! I have problem with buffer size (width) in package rgeos. I would like to expand given geometry (points) to specified width based on the z value from attribute table. Here is example: point <- data.frame(x=c(10,20), y=c(10, 10), z = c(2,7)) point_shp <- SpatialPointsDataFrame(point[,1:2],point) plot(point_shp, xlim = c(0,30), ylim = c(0,20)) plot(gBuffer(point_shp, width = 5,

On looking more closely, the purpose of finding the class definition is to update the entry for the new relationship, as the warning message suggests. That requires that the namespace holding the definition be writable. In the case of subclass information, the original namespace is very likely to be locked, if it's not the package currently being loaded. Copying the definition in order to

Dear List, I'm building a package that uses 2 functions of the 'sp' package, and I declared them in my NAMESPACE file as follow: importFrom("sp", proj4string, coordinates) The package is built without any problem, but when I load the package, I get the following message: " Loading required package: sp Note: polygon geometry computations in maptools

I'm trying to keep debugging of a development package relatively sane. I see that some packages manage to incorporate what appears to be Subversion (SVN) revision information in the package description; for example, > library(MASS) > sessionInfo()$otherPkgs$MASS$Revision [1] "$Rev: 3016 $" which looks like an auto-generated revision number. On the other hand, the rgl

Hi R-user, I was trying to make a raster map with WGS84 projection in R, but I could not make it. I found one data set in Google that data is almost the same format as of mine. I wanted to make a raster map of temperature with 1 degree spatial resolution for the global scale. I could make it in GIS software but I do have many variables (to be many raster images) and ultimately I am importing them

The third report on the R-spatial evolution project has been published. https://r-spatial.org/r/2023/04/10/evolution3.html It links back to earlier blogs and presentations, and focuses on work that maintainers of R packages and workflows using rgdal, rgeos and maptools need to put in train now before the packages are archived on CRAN. The first changes will occur in June 2023, and the

Deberías instalar también, como poco, ggmap. RStudio no suele venir nunca mal. No sé si hay wifi en el bar para instalar las últimas dependencias... Un saludo, Carlos J.

Qué tal, buen día. He estado intentando instalar el ggplot2 en R studio, pero me dice que ggplot no está disponible para la última versión que es la 3.2.2, ya descargué la 3.1.1 también y tampoco está disponible para esa versión. Saben qué versión puedo descargar para poder instalar el paquete de ggplot2, ggmap, rgdal, rgeos, maptools, dplyr and tidyr, tmap. Gracias! [[alternative HTML

Hola a todos: efectivamente, esas son las librerias que convine tener instaladas. Llevaré los datos que utilizaremos en un pendrive (por si acaso falla la wifi) y también el *.md del código para poder seguir la demo sin escribir todo el código! Para esto, yo creo que lo mejor es abrir el *.md con R Studio. Esta tarde nos vemos! -- Beatriz Martínez @_bmartinez_

Hola Beatriz, Si me pasas el *.md lo subo a un Dropbox y si no es muy grande lo subo a R-Hispano (linkándolo a la agenda).... Saludos, Carlos. El 29 de octubre de 2013 15:56, Gregorio R.

I have been using the sp package to deal with gridded data. I would like to know how to extract the vertices (x,y) of polygons that outline areas of like-valued cells in a grid. Here is a simple 3x3 grid: 2 2 1 1 2 1 1 1 3 x <- c(1,1,1,2,2,2,3,3,3) # define a 3 x 3 array of points y <- c(1,2,3,1,2,3,1,2,3) h <- SpatialPoints(cbind(x,y)) # make these an sp object of the points
