Dear forum,   I am working in R 2.9.1 and I am trying to sample locations from a network file. Reading in nor plotting is a problem, however when I am trying to sample from the file I get the following message:   nwlim<-readShapeLines("C:/Limburg_nwshape", proj4string=CRS("+init=epsg:31300")) plot(nwlim)   randacc<-spsample(nwlim,n=1000,"random") Error in function (classes, fdef, mtable)  :   unable to find an inherited method for function "coordinates", for signature "nu...

I have a shape file as poly line and I want to convert it to polygon.Is it possible to do that in R?lake <-readShapeLines("./lake_main_utm.shp")proj4string(lake) <- CRS("+proj=utm +zone=39 +datum=WGS84") Sincerely. [[alternative HTML version deleted]]

...al distribution of the precipitation within an area. However, I think some thing wrong with the way to create the matrix for the precipitation data, so it came out lots of stripes. Could somebody help to see what's the problem? Here's the code: library(maptools);gpclibPermit() KSR <- readShapeLines("/Users/R/Code/data/KS_River_Basin_Dissolve.shp") states <- readShapeLines("/Users/R/Code/data/statesp020.shp") ppt <- read.table ('/Users/R/Code/LULC/pptnewlulc.dat', header = FALSE) # the size is 5764(pixels) x 528(periods) ppt <- (ppt/100)*25.4 #convert from...

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

I'm running windows xp, R 2.3.1 with maptools 0.6-6, I guess. When plotting from a large SpatialLinesDataFrame and using xlim & ylim to reduce the area, the plot axes automatically have the same scale size, even if xlim and ylim ranges differ. E.g.: tmp <- readShapeLines(filepath) plot(tmp,xlim=c(-126,-119),ylim=c(50,51)) The y-axis range is actually 47-54, same range as the x-axis. What am I doing wrong? Should I be using a different object for simple coastline & river data? Thanks in advance! Michael _______________________________________________________...

I imported the attached tiff file and converted the coordinate system to long lat and graphed it: californiatiff<- readGDAL("california1.tif") proj4string(californiatiff) > rasterprojection <- spTransform(californiatiff, CRS("+proj=longlat") however, when using the plot command for rasterprojection, I get a blob. I can see the outline of the state of california and
