Regards. I'm a beginner in programing, so I have a basic question for you. If someone could help me please.. I want to create a function, which will be able to export files from excel. I tried with a <- read.csv(file, sep =",", as.is = TRUE, row.names = 1, header = TRUE), .. but instead of numbers, it gives me strings for example: "299,311". I can handle this string

Hello to all again :) Again, I have an issue with my homework. I was troubling myself for two days, and I still can't get it :( So, if someone can help me, I would be so grateful... HOMEWORK 1. I need to draw function, random walk take the length of walk, and its in 2D. As a result, I have to take matrix in which are i-lines of matrix, written coordinates on i-steps radnom.walk <-

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 R users I need the map of France?s ? communes ? (towns) to build a map Is there a way to get it? More generally: How to do to get the map of a country and its different geographical levels?

Hi list, Well, this time I’ve a doubt with mapping generation. I was already able to read and plot shapefiles, plot point on this map. All this without any problems, but now I want to do something that I think, only Golden Software Surfer is capable of. I would like to plot a kriging result on the existing map (map script below). Well I looked for on the net, but I was not able to be sure of

Hi ALL, Can you please help me on how to determine the prediction error for ordinary kriging?Below are all the commands i used to generate the OK plot: rsa2 <- readShapeSpatial("residentialsa", CRS("+proj=tmerc +lat_0=39.66666666666666 +lon_0=-8.131906111111112 +k=1 +x_0=0 +y_0=0 +ellps=intl +units=m +no_defs")) x2 <- readShapeSpatial("ptna2",

Hi list. I would like to know how do I insert a North arrow, stored as a png file in my computer, in a map? I found lots of post asking similar things, one of them mentioned the pixmap package. The map was done using map() and shapefiles (the code is below). I’m using the pixmap () and addlogo() functions. Well I can import the png with pixmap() function (I guess, once there’s no error message),

Hi guys i need some help to build choropleth. Basically i am trying to colour regions on the map by population. I possess the shape file of the country, and also the population data, however, i am having trouble to create the plot, below is my code: population=read.csv("nz2.csv") population names(population) nz=readShapeSpatial((sprintf('nz-geodetic-marks',tmp_dir)))

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

I have obtained shapefiles for Indian states from here: http://www.maptell.com/index.php?option=com_remository&Itemid=159&func=fileinfo&filecatid=115&parent=category Problem: I want to extract centroid coordinates for each State, but there is some coding problem with the shapefiles that prevents this. #Code: #After extracting the shapefiles from the india_state.zip file, then:

Dear all, I am trying to create a map for central asian countries(Kazakhstan, Uzbekstan, Kyrgyzstan, Turkmenstan, and Tajikstan). I tried google for shapefiles and Rdata files of central asia, but I can't seem to find them. There is only a world map and individual maps for each countries. If I use individual maps to create this map, how do I put them on a same graphic with different colours?

Hi, I want to use map("state") and have the ecoregion shape (please see link) file projected onto this. ftp://ftp.epa.gov/wed/ecoregions/cec_na/NA_CEC_Eco_Level3.zip ftp://ftp.epa.gov/wed/ecoregions/cec_na/NA_CEC_Eco_Level3.zip Could someone please show me how; I have never messed with this sort of thing.

Dear all, in GADM map there are three levels (nation, province and precinct) for each country of the world but for all of them you are never able to plot only one part of a chosen country. To be sure, I am trying to plot only one region of “Italy” and colour the different precincts in it. So far I am able to colour only the part of my interest but the programme still plot the whole country. Is

Dear list, I'd like to use the function smooth.map{maps} to smooth out aggregated spatial data. The first argument to this function must be a map object. I have a shape file which I read with readShapeSpatial{maptools} and I got an object of class "SpatialPolygonsDataFrame". Is it possible to create a map object from a SpatialPolygonsDataFrame object? Alternatively, is there any

Hello all, Working on mapping some probabilities using R to a geographic unit called a TAZ. The below data will work but you will have to set your directory for the shape file. Never did this before so hopefully this works. ResProbs is just supposed to be a value between 0-1, sorry if that more complicated than it needed to be. TazFile <- "*directory*/TAZ.shp" TazShape <-

Dear list, I have a question regarding the included polygon in the khat function of the splancs library defining the area where points appear. I have not only one simple polygon included, my map includes several islands. I read my map which was a shape file by readShapeSpatial of the maptools library. Then I split up the SpatialPolygonsDataFrame into the included polygons by coor <- NULL

Hi, I have a data frame listing US counties and a quantity ("number") per county and I have a shapefile of the US with county ID's. I would like to plot the "number" variable on a map (in the shapefile) using a color range per county (e.g. white = min(number) = 2, black = max(number) = 15). Can anyone help me actually plotting the data on the map? This is how far I got.

By any chance has anyone put together the R code for reproducing the Firefox Downloads Analytics Map in R? Here is a link to an example: http://www.knitwareblog.com/wp-content/uploads/2008/06/firefox-3-download-map.jpg I'll try to track down the inputs, but I am interested in putting the code to produce this or something similar.
