I am regularly running into a problem where I can't seem to figure out how maintain correct data order when selecting data out of a dataframe. The below code shows an example of trying to pull data from a dataframe using ordered zip codes. My problem is returning the pulled data in the correct order. This is a very simple example, but it illustrates a regular problem that I am running into.

i've search the email archives, searched the documention of various map packages and done an R-site search, but have been unable to find direct resources for creating maps of the US that are colored or annotated or ... by zipcode data. For example, create a map of the US and color each zipcode region by its population using two vectors z,p containing the zipcode and population,

I''m stuck in a catch-22 type problem. I have an insert form for a table that uses the validation in the model. i.e. When you click submit on the form and haven''t filled in the required fields then you get the nice rails error messages saying "field can not be blank". This works fine until I introduce some more logic. What I''m trying to do is to validate

#################################################################################### We have used maptools to construct state, county, township, census-tract, and zipcode level R maps with an Albers Conical Equal Area projection.

Dear all, i have a programming problem that should be simple, though i am stuck with it. Please note that this is not a specific geonames problem, though i use it as an example - it´s just a basic problem with lapply. I use the geonames webservices with the R geonames packages which works almost smoothly. I have a vector of Zipcodes and i want to do a geonames lookup for all of them, which

Good evening! I''m currently trying to submit some data and a file upload through Ajax. I''m using rails & prototype, and somewhere there''s a disconnect. I''m reasonably convinced the file upload isnt being sent at all, or if it is, Rails has absolutely no idea. The form itself heads with: <form onsubmit="new

Hey, Does anybody know of a good Geocode library for Ruby, similar to Perl''s Geocode::Postal, that i could use in my rail app?

Hello R-helpers, I am trying to search for string that includes the caret symbol, using the following code: grepl("latitude^2",temp) And R doesn't like that. It gives me: > temp<-c("latitude^2","latitude and latitude^2","longitude^2","longitude and longitude^2") > temp [1] "latitude^2" "latitude and

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

Hi list, I have a problem to solve which I believe I shoudl use the convolve to solve it, but I could not figure out how to do it. I got mydata, which is a dataframe which has 7 locations, each location has a longitude,latitude and a value. considering a step of 0.5 degree for longitudes and latitudes, I got 15 points for longitude and 15 points for latitude. Then I created a grid, mygrid, which

Hi Everyone, I am new to R Language and was wondering if someone could help me convert my latitude-longitude coordinates to cartesian coordiantes using geoXY() from SoDA package? I have been uploading my coordinates from a text file into R (they originate as a dataframe) and them converting them to a matrix using the data.matrix() function. But I think I'm running into trouble when I try to

Hi, i am using spatstat package for spatial data analysis and now i have a problem to create a point pattern. The points are in file "points.txt" (first column for Latitude and second column for Longitude ) and I imported them and separated each columns in two arrays x and y. If I plots x and y ( e.g plot(x,y) ) the result appears in square area without problems and the scale is

Dear R Users, I am using the reshape package to reformat gridded data into column format using the code shown below. However, when I display the resulting object, a single column is fomed (instead of three) and all the latitude values (which should be in either column one or two) are collected at the bottom. Also, the NA values aren't removed, despite this being requested in the code. Code:

Dear R-Helpers, Is there a way to draw shaded (filled) polygons in panel graphs produced by xyplot ? I made different trials (see below) with polygon() and grid.polygon() but polygons are not drawn (probably for the same reason that prevents the use of lines, points, etc. in xyplot panels).

I have 100 data files, which contains very huge data sets of location details ( e.g latitude, longitude, time, temp) Now I would like to save the all data of these 100 files in r object, so I can reload data any time. * Every file has different length of data latitude <- NULL longitude <- NULL time <- NULL temp <- NULL for ( i in 1:100) { data<-
