Hi All, I'm new to R and wants to read XML file as R data frame. Is there any package that could be used for this purpose. I will really appreciate your response.

Hi All, I am new to R and don't know how to achieve it. I am interested in generating a hypothetical dataframe that is consisted of say two variables named v1 and v2, based on the following constraints: 1. The range of v1 is 500-1500. 2. The mean of v1 is say 1100 3. The range of v2 is 300-950. 4. The mean of v2 is say 400 5. There exists a positive trend between these two variables, meaning

The goal is to test a developed model against two sets of hypothetical data, where the relationship between on data set is linear whereas non-linear (e.g., polynomial) with another. However, the distributions of the v1 and v2 should not be other than normal or slightly positively skewed or slightly negatively skewed. In Oracle, random data is generated with packaged function

No its not. I am doing all these experiments for my own learning purpose. I am Oracle SQL & PLSQL programmer and I can do these things with Oracle analytical functions. However at present I am keen to learn R, with no other interest right now.

The Problem ----------- After using a join in my find the id attributes set in my Entity objects are wrong! It is setting the Entity id to the value from Postcode id! The Code -------- entities = Entity.find(:all, :conditions => [...omited...], :joins => "as e inner join postcodes as pc on substring_index(e.postcode,'' '', 1) =

Dear R-helpers, I get GPS readings with bug counts (bugs meaning insects in this case) made along rows in crop fields and use these to make maps of bug distribution. The GPS readings are not quite accurate enough for my purpose, so since I know what row each reading is made in, I adjust the latitudinal coordinate using: grd<-lm(lat~lon+Row,data)

hi, i have a longitude vector (x) a latitude vector (y) and a matrix of bathymetry (z) with the dimensions (x,y). I have already succeeded in plotting it with the image.plot (package 'field') and the contour functions. But now, I want to make a grid in order to extract easily the bathymetry corresponding to a couple of longitude, latitude coordinates. Do you know a function or a

Hi All, I''m having a problem with Rails truncating latitude and longitude values. In my database (mySQL) table, my lat/lng columns are defined as Decimal(25,20), but I get different precision values depending on what I do. If I post, via XML, a value of 37.436490000000006 to my controller, what gets inserted into the db table is 37.43648999999999900000. Then, when I fetch the record in a

I see several mapping libraries but cannot find how to do a simple task. Starting with a vector of zip codes (in the United States and in Canada) I would like to automatically lookup the corresponding coordinates. Can you suggest a package and function that I should turn to? I would also like to automatically pull in the altitude, and some climate data. -- Farrel Buchinsky [[alternative HTML

I am trying to set up a Grass project and need to set up the region so that I can view the map. I can look at a map and find the lat/lon, but the map projection is in UTM NAD38 WGS84 and I need to set the eastings and northings. Is there a package that will help me calculate this in R. thanks -- Stephen Sefick Let's not spend our time and resources thinking about things that are so little

Hi Team, Need your guidance in building SPDF objects from Latitude, Longitude Information available. I am using package "plotGoogleMaps" which is really awesome but it requires SPDF objects to build the maps. I have a data frame which have Latitude and Longitude information and wanted to convert it in SPDF for making maps. Please help me to find suitable package or function to convert

I have a dataset giving traffic between pairs of ports, and the lat/lon of each port, roughly as follows: sample data as follows > df2VisitTrips[1:4,] Origin Destination NumberOfTrips OriginLatitude OriginLongitude DestinationLatitude DestinationLongitude 1 P1 P16 1 39.45965 -80.15633 40.76111 -79.54583 2 P1 P3

Hi all, I would like to know a way of calculating the distance between 2 points when I already have the longitude and latitude of the points. For example : Point 1 : 52? 9'54.00"N 4?25'8.40"E Point 2 : 52?27'46.80"N 4?33'18.00"E Distance between point 1 and point in km .... Is there any functions already available for this ? Any help will be much

Good day to you all, I have lightning data containing date, time, latitude and longitude. I hope that distribution of latitude and longitude will give number of lightning occurrence in a region. I have used factor function to sum up the number of events on latitude and longitude axis and saved as x and y. But when I tried to plot the two, I had and error message ( Error in image.default(x, y, z) :

Does anyone have any experience retrieving latitutde and longitude for an address from the Google Maps API? I'd like to have an R script that submits a street address, city, state, and zip code and returns the coordinates. So far, I've been submitting the coordinates from another program, then loading the coordinates in R and merging them back into the data frame I want to use.

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, does anyone know a way to get the address and a list of house numbers from a Post Code? Is their an online web service that will do this? I''m creating an app for a chinese take-away and this functionality is important. What do you think is the best way of achieving this? for UK post codes.
