similar to: Geodata SQL statements with multiple results in the controller

Hey guys, I''ve been hearing a lot about erubis: http://www.kuwata-lab.com/erubis/ Especially about how much faster it is than straight ERB. In their Ruby on Rails support docs: http://www.kuwata-lab.com/erubis/users-guide.05.html#topics-rails They state that with a few added lines to your environment.rb it will replace ERB completely. I''m wondering if anyone has done this in

Hey, I have a data set of 1.20MB. I used read.table( ) to read in the data and then tried to convert it to geodata type. But it failed and I got "Error in vector("double", length) : cannot allocate vector of length 1351974000" message. All the commands I used were: rawdata<-read.table(file=" ") datag<-as.geodata(rawdata) BTW, what is the biggest origin

Sorry, this is probably quite an easy question, but I'm new to R and couldn't find the answer anywhere. I'm using geoR and geoRglm, but can't figure out how to get a border in my geodata object. Does this need to be defined when I'm importing my data, or afterwards, and how do I go about doing this? Thanks -- View this message in context:

Hello, I'm new to this list. Sorry if my question or parts of it already came up before. For my research in geostatistics, I am working with large sets of data in R (basically large matrices containing discrete x and y coordinates and a value for a certain parameter). These sets are obtained by kriging. The operation I'd like to perform is smoothen the output data set. I want to do it by

I used points graphic (geoR) in this way: points(zn,pt.divide=c("quintiles"), main="Location map of Zn",lambda=1,col="gray",yl="coord y",xl="coord x",x.leg=0. 3, y.leg=5.5,dig.leg=2,cex.min=0.5,cex.max=1,) Can I reduce legend characters (a sort of cex)?

Hi everyone, I''m writing a lightweight AJAX application using Rails on the server side as a RESTful web service provider. I need the web service to support both JSON and XML I/O. Outputting data in XML and JSON is easy (using to_xml and to_json), and it''s also easy to do XML input as Rails does it for you automatically. Is it possible to somehow have the same automatic parsing

See the blog post at http://blog.lonestarsoftware.net/2007/03/09/active_resources-010-released/ Reading through the rails blogosphere last week, I read a post (which I can not find again) that suggested a completely different approach to AJAX use in rails apps. The idea was to create a Javascript proxy to the ActiveRecord models and allow AR operations to be called from the client. I see this

Hi, I''m new. ;-) I creating a little rails app, that will crawl the web on a regular basis and then show the results. The crawling will be scheduled, likely a cron job. I can''t wrap my head around where to put my crawler. It doesn''t seem to fit. An example: Model - News Story Controllers - Grabs a story from the DB, Sort the Stories, Search the Stories etc. View -

Hello I need to check that the NHS numbers in my database are valid. I''m storing them as ten-digit strings: the first nine are the identifier and the tenth is a check digit. There are four steps to calculating the check digit (from http://www.connectingforhealth.nhs.uk/systemsandservices/nsts/docs/tech_nn_check_digit.pdf): 1. multiply each of the first nine digits by a weighting factor

I would like to be able to do the xyplot in ggplot below. I read in the archive that Hadley was working on this for the next release, and I can not find the documentation (Aug. 23rd). River.Mile <- c(215 ,202, 198, 190, 185, 179, 148, 119, 61) Cu <- rnorm(9) Fe <- rnorm(9) Mg <- rnorm(9) Ti <- rnorm(9) Ir <- rnorm(9) r <- data.frame(River.Mile, Cu, Fe, Mg, Ti, Ir) z <-

I would like to do the following in ggplot: what am I missing?

I would like to Summarize values that are repeated measures at a certain river mile with box plot i.e. The data matrix looks like this 123 124 125 #fiver mile 0.5 0.6 0.7 0.4 0.5 0.6 ... ... ... #values I would like to make a boxplot with the river mile naming the different box plot. How do you suppress the X123? Stephen -- Let's not

This is what I would like to do and it works just fine. Is there a way to shorten this code so I don't have to subset a subset of a subset? d<-subset(subset(subset(subset(x, River.Mile<=202), River.Mile>3), Lagrangian=="Yes"), EventType=="Regular") Stephen -- Let's not spend our time and resources thinking about things that are so little or so large that

Quick question. Say I have a geographical database with counties and zip codes where counties have and belong to many zip codes. zip_codes (id, zip_code) counties (id, name) When I create the association table, the Rails way says to do the following: counties_zip_codes (county_id, zip_code_id). However, given that zip_codes.zip_code is itself a candidate key, I would much prefer to do the

Hi there, I'm having problems with the Grandstream Budgetone 101 on hangup - "show channels"/"show channels concise" output is still showing the call's channels as active. The problem does not exist when I use SJPhone, so I'm assuming it isn't an Asterisk configuration issue. Has anyone seen this, or better, does anyone have a fix? :) Thanks, David. --

Hey all, I''m rather new to Ruby and Rails (and not great with SQL), but I''m developing a ride sharing app and would like to be able to sort on something I don''t have stored. I have users, events, and rides, each of which has a zip code. Events have_many rides, and rides belong_to events. When an event is selected, I''d like to be able to show a list of

The application I''m developing allows people to create events in their local area; as part of this feature I want to display a list of, say, the five most recent events within 30 miles of a person''s location. I have a User model and a Profiles model which contains the user''s location (city, state, zip code) among other non-related personal information. So what I would
