similar to: Wrong values when projecting LatLong in UTM

Hi, my mapstraction onclick event handlers always yielded javascript errors in Virtual Earth maps ("e.view is undefined"). I''m using version 6 of mapcontrol.ashx. After consulting Virtual Earth documentation, I came up with a solution. Here is my patch (based on rev 212) > var that = this; 360c361,368 < me.clickHandler(e.view.LatLong.Latitude,

Hi R-Users, I have plotted a region whose polygon coordinates are given in shp format ED50 UTM (zone=30) ) using "readShapePoly" in library(maptools). Now I need to plot a set of points in that region (my.dataframe, with X and Y geographic coordinates), which have been read using GPS in Longitud-Latitud form (using WGS84 system), so I first need to convert these Longitud-Latitud data

Dear all: I have a shapefile in UTM coordinate system and I would like to transform it to Lat/Log coordinates (WSG84). The package PBSmapping contains function convUL to transform between the two coordinate systems when data is in the form of a data frame with attributes specifying the coordinate system. However, when shapefiles are imported using function read.shape (package maptools), a list

I''ve recently been looking at Mapstraction as a way to make it easier for me to support more than one mapping service, mainly Google Maps and Microsoft''s Virtual Earth. However, I seem to be running into a lot of errors when trying to use Mapstraction with IE7 and Virtual Earth. As an example, I get a "Not Implemented" error when I load the many of the demos. This

Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails.

Dear R-helpers, I know how to use unique to select unique rows, e.g. unique.rows<-unique(dataframe) but I would like to select those rows that are unique only only TWO of my dataframe's columns (so, two rows with the same value on these two columns would not be kept, even if they had different values in other columns). For example, I have a dataframe with 10 columns, two of which are

Estimado Jose: En nuestro caso utilizamos las mismas librerias y solemos resolverlo asi (donde el color depende del valor que se le asigne) //-------------------------------------------------------------------------------------------------------------------------------------- #configuramos donde setwd("D:/mapas/") #Carga de librerias library (sp) library (RColorBrewer) library

Used a great howto @ http://iamrice.org/articles/2005/12/09/using-google-maps-in-the-uk-with-rails for using google maps on uk sites. Just having one issue I can''t seem to work out how to draw the postcode from my table I keep getting hit by method errors. The controller is require ''postcode_2_latlong'' postcode = Postcode.new("TN22 2LG") # I want this to

I am trying to read some data off the zillow site. Newbie to xml, html, parsing and the xml package. I've been able to load the web page I'm interested with the following code but I'm not sure of the next step to get the information I'm interested in into R : library(XML) url <- "http://www.zillow.com/homes/511 W Lafayette St, Norristown, PA_rb" doc <-doc <-

Dear all, I am trying to project my LongLat-maps to a plane. The ultimate purpose is to do a search of points in vicinity of other points using overlay-commands (sp) with radius in km. I am applying spTransform (package rgdal) and it gives my some curious results. An example. Let's take a point lying somewhere in Germany, zone=32U x <- 8.968735 y <- 49.454735 After conversion I

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 all, I have been trying to convert coordinates from longitude/latitude to utm but I got an error. As soon as the longitude coordinate is greater than 90, I get the folloowing error message: "error in pj_transform: latitude or longitude exceeded limits" Here is what I did: SP<-SpatialPoints(cbind(126.59,-14.30),proj4string=CRS("+proj=longlat"))

Hi, I'm trying to use transform my mercator locations into utm but I'm doing something wrong because only x is transformed ... see > xy.sp SpatialPoints: loni lati [1,] -8.85 38.16 [2,] -9.19 37.99 [3,] -9.11 37.97 [4,] -9.06 38.15 [5,] -9.03 37.87 [6,] -9.14 37.81 [7,] -9.09 37.70 [8,] -8.95 37.45 [9,] -9.17 37.37 [10,] -9.00 37.34 Coordinate Reference

Hi there: I am a total beginner in R, and I have a simple question: I have a table with thousands of lines that represent locations, and two columns: latitude and longitude. I need to randomly sample 1000 lines. How do I do it? I know the command "sample", but it samples elements independently, not lines. If there is a better place for me to ask that type of question, please let me

Hello all and thanks for the help. I am analyzing a dataset using MetaMDS and I would like to project some extra samples onto the plot such that the extra samples do not play a role in defining the axes. I have been thinking of different ways of doing this and I was wondering if anyone had a suggestion for an easy way to do this (possibly a way to weight samples in the analysis?) Thanks --

Hey all, I'm new to the forums, but not new to Wine/Linux. I'm having a bit of an issue. Playing with winetricks, I've gotten the Liteshow Manager install file to start and install up to 70% where it then fails. The application itself stays open, but it lets me know the installation fails. There's no logfile or explanation of why it fails. I'm able to wirelessly connect to

Hello; I want to create a 2 D plan with (123 values) for axis1 and 7 values for axis 2. I then want to make a projection of points with their coordonates in that plan! is that possible and how to proceed? Thanks [[alternative HTML version deleted]]

Hello, I have a survivor curve that shows account cancellations during the past 3.5 months.  Fortunately for our business, but unfortunately for my analysis, the survivor curve doesn't yet pass through 50%.  Is there a safe way to extend the survivor curve and estimate at what time we'll hit 50%? We started a new program 3.5 months ago, and I believe that this set of accounts behaves
