hi, i have a noob question. how do i create a table but add additional fields? for example.. i have a total_table of total, county, and town where total_table inherites county_id and town_id from my town_county table where county_id has_many towns. in my view, id like to go through the hash like this table total_table for total_table.county { print total_table.county print

hello, i am having trouble on how to implement this. i have a table of doctor information where each doctor has a town and county field. i would like to create a view that shows the amount of doctor_types in each town. For example if the user selects the ''General Doctors'' search button, a view like this will show up. The next step would be for the user to select which

I''m having some really weird problems with an app I''m writing. Everything is working as expected on my development machine (OSX, Rails 0.14.4) but is cacking out with weird errors on the Textdrive demo site (FreeBSD, Rails 1.0.0). It complains about missing variables, with errors like this: undefined local variable or method `rawcode'' for

Dear Rers, is there a way to color counties on a full US map based on a criterion one establishes (i.e., all counties I assign the same number should be the same color)? I explored a bit and looks like the package "maps" might be of help. library(maps) One could get a map of the US: map('usa') One could get countries within a US state: map('county', 'iowa', fill

I am using "maps". I am running the following code to get this list of all the counties: map('county', plot=FALSE)$names In the output, all counties have first the state listed and then, after a comma, the name of the county. However, county # 2395 (State = south dakota) has no county name. Anyone knows what this county is? Thank you! -- Dimitri Liakhovitski

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, I would like to plot a map of US counties using different colors. map() seems to be the function to use, e.g. library(maps); map('usa'); map('county', 'colorado', add=T,fill = T, col=c(1:5)) plots Colorado counties using colours 1 to 5. However, I want each color to represent a certain value - a value to be picked from a data frame. This code should show a

Hi, I have a question which is a little off-topic but then again, it should stay in the boundaries of what can be done with available R functions. Has anyone pointers to tutorials or the like where one can get inspiration on how to visualize some "spatial" statistics? I want to analyze different statistics of 60 counties in a country. I have a shape file for those counties thus I can

Hi, I'm having a bit of trouble with 'scales="free"' in the segplot() function of latticeExtra. Say we need panels for each year, showing only those counties that are represented in each one: ---<--------------------cut here---------------start------------------->--- library(latticeExtra) data(USCancerRates) uscr.w <- subset(USCancerRates, state ==

Dear R'ers, I am wondering what is the smallest geographicterritorial unit available for formatting in Canada. Provinces? I know that in the US it is the county so that I can color US counties any way I want, for example: ### Example for coloring US counties ### Creating an ARTIFICIAL criterion for coloring US counties: library(maps) allcounties<-data.frame(county=map('county',

Hi, Four tables: users, user_counties, uk_counties and us_counties. Each user has many counties, and each county has many users, so I decided to make user_counties a polymorph, so it can have counties from different countries (each country requires a completely different set of tables with a completely different set of properties, that''s why there''s one table for uk_counties and

Hi, I''m developing a Rails app which uses dynamic forms. To implement these, I''ve used AJAX and Rails''s built-in form observers. Unfortunately, I''m having a problem. This is how the form starts: * Country select box [OBSERVED] (Republic of Ireland selected) * County select box [OBSERVED] (none selected, list of Republic of Irish counties in the drop down)

Is there an R equivalent to SAS's proc gremove? You would use this procedure to combine the units on an existing map, for example to build a map of Metropolitan Statistical Areas (MSAs) from the [US] counties dataset where the internal boundries surround the MSAs (which are groups of counties) rather than the individual counties. I can imagine the mechanism would be to find and erase the

Dear R Users,I have a data set with several variables. One of these variables is the number of farms per county and I'd like to split this variable into two domains: (a) counties with fewer than 600 farms and (b) counties with 600 or more farms I've tried solving this problem for hours, but I'm new at R so I'm not getting there. if (x < 600) y <- x else z <- x didn't

R-listers, I'm working on a project where I need to get the lowercase of the county variable in a dataset alike to the example below (only difference is that the full dataset has all the states and counties in the southeast United States). I keep getting this strange error with the lowerize function (which didn't occur the first few times I use the code below), and oddly enough the error

Hi, I''m trying some RJS to update a series of list boxes in which the user selects a state, and the following list gets updated with a list of counties, and the same for the next list of areas. My code works perfectly (albeit a bit slow) on Firefox, but on Internet Explorer it clears the list box (instead of filling it) and Netscape shows all the counties cramped together on one
