Greetings: I would like to kindly ask for a little help. The rough code is: #________________________________________________________ dat=data.frame(read.delim(file="all.txt", header = TRUE, sep = "\t", quote="\"", dec=".",na.strings = "NA")) nc=read.shape("astae.shp", dbf.data=TRUE, verbose=TRUE) mappolys=Map2poly(nc) submap

Dear R experts, I am new to the list and R software. I need to convert arcview file to Winbugs having R has middle package. Got from friends that it is possible following the steps: 1. Converting arcview shapefile to "cgm clear text file" 2. Downloading "convert.r" to into R 2.1 use source("convert.r") 2.2 convert("filename_cgm") without the

Using the maptools function "map2poly" I have created a map/polylist object - a map of the Great Lakes. My goal is to passively plot additional data on this map. Unfortunately I am not able to change (distort) the relative scale of the axes for the map, and so the sample points do not line up correctly on the map. In the code below, notice that I have set the same axis ranges on each

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

Hi, In another thread ("PBSmapping and shapefiles") I asked for an easy way to read "shapefiles" and transform them in data that PBSmapping could use. One person is exploring some ways of doing this, but it is possible I'll have to do this "manually". With package "maptools" I am able to extract the information I need from a shapefile but it is

Hi: Is there any function in R which can convert the long/lat to UTM(Universal Transverse Mercator)? There are quite a few converters on Internet. However, the interface is designed as input->output which I can not convert lots of locations at the same time. Another question is whether there is a function in R which can tell the time zone from the location's lat/long? Thank you!

Dear R users, I use R 2.4.0 on an iMac running Mac OS X 10.4.8, with a 2.16GHz Intel Core 2 Duo and 2GB 667 MHz DDR2 SDRAM. > sessionInfo() R version 2.4.0 (2006-10-03) i386-apple-darwin8.8.1 locale: es_ES.UTF-8/es_ES.UTF-8/es_ES.UTF-8/C/es_ES.UTF-8/es_ES.UTF-8 attached base packages: [1] "methods" "stats" "graphics" "grDevices"

hello. I am trying to read a big file with different sections each with a different format, actually it is a map in format *.e00 of MapView. I can read the whole file with no problems from R using scan() but it takes too long, some files are 50 meg and have to be read line by line to catch the section codes. So if I do the reading from C would it be faster? if it is, how do I manage with the

Hi, Is there any way to plot a Map with different shading patterns, instead of color intensity, in R2.0.1 over Linux ? Thanks.

Is there a way to generate maps in R. Specifically, I have calculated estimates of intra-regional inequality for US states, and would like to project that information onto a map. Thanks, Nirmala

Dear all, I am interested in plotting maps visualizing spatial statistics in an aggregated fashion, according to administrative boundaries. Partially, I want to visualize some spatial data for administrative units (autonomous republics, oblasts, krays) of the Russian Federation on a geographical map. I have found the maps package (and related) and would like to use this package e.g. in a kind

Hi list. I would like to know if someone had already successfully loaded and Arc/Info Ungenerated (.dat – extracted from http://rimmer.ngdc.noaa.gov/mgg/coast/getcoast.html) file on R. I’m able to do so with shape files using maptools functions, but these ungenerated data are making me crazy. I don’t have any of ArcGIS tools (one of them probably can do that), and I can’t find any free tool that

Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors. For example: a map (shapefile) with 10 countries, 15 points in the polygon of country A, 20 points in the

Hi - I'm trying to plot a map from a shapefile and then colour different areas of it depending on different attributes of those areas. A couple of years ago I used some code to do this that would plot a map in R from a shapefile (states within a country). It then uploaded a .txt file which had the same number of rows as the shapefile and one column populated with numbers from 1 to 8 which

Hi! I have no idea if this is maybe an easy task utilizing R since I read there is geographical map data in some package: I have a huge number of geographical points with their coordinates in Germany. Now I want to determine for each point in which "Bundesland" = state it is located. Can anybody tell me if this is doable relatively easy in R and if so give me some hints or links

I am a very new user of R (ver 2.2.1 & Windows XP) I would like to see if I can plot some simple data (Number of people in certain regions of Canada and within Ontario and Quebec. Can anyone suggest a) a souce of Canadian maps and b) some simple worked examples of using maps. At the moment I have managed to load the map and mapdata libraries but that is about the extend of my knowledge.

Hi list, I would like to know about any proposed XML representation for tc objects hierarchy. I found something at "LTCM, a Linux QoS API Library" (http://artemis.av.it.pt/~ltcmmm/) that looks like a start, but any others are welcome. I''m starting a project to automatically syncronize traffic shape rules between servers and thought XML is the best way to represent tc

Dear R people, I am wondering how difficult it would be to produce graphs based on maps in R (like "a county is red where x is high"). I reckon this requires the coordinates for the polygons that make up the map and also a mapping to a set of identifiers to assign colours, hatches, etc. Would it be possible to pass R a vector graphics of the map and back out the polygon definitions

Dear all, I am interested in plotting maps visualizing spatial statistics in an aggregated fashion, according to administrative boundaries. More specifically, I have fitted a cross-section model on data regarding Italian "counties" (province, for Italian readers) and I would like to visualize residual behavior on a map, in order to have a first assessment of their spatial

Dear Steve, I'll post your question also to the R-help mailing list since I think this can help to other RArcInfo users. As I mentioned in the last release of the package, I have a tutorial nearly finished. I hope to release it in the next days. > I have downloaded an .e00 file of 2000 Census Tracts for the southern US > State of Georgia, and I'm wondering which steps I need to go
