Dear R list, I have a dataset with a column which should be read as character, like this: name surname answer 1 xx yyy "00100" 2 rrr hhh "01" When reading this dataset with read.table, I get 1 xx yyy 100 2 rrr hhh 1 The string column consists in answers to multiple choice questions, not all having the same number of answers. I could format the

Dear Help-Rs,   I've been dealing with this problem for some time, using a work-around to deal with it. It's time for me to come clean with my ineptitude and seek a what has got to be a more streamlined solution from the Help-Rverse.   I regularly import delimited text data that contains numerics enclosed in quotes (e.g., "00765288071").  Thing is, for some of these data, I need

If read.csv's colClasses= argument is NOT used then read.csv accepts double quoted numerics: 1: > read.csv(stdin()) 0: A,B 1: "1",1 2: "2",2 3: A B 1 1 1 2 2 2 However, if colClasses is used then it seems that it does not: > read.csv(stdin(), colClasses = "numeric") 0: A,B 1: "1",1 2: "2",2 3: Error in scan(file, what, nmax, sep,

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

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 am interested in locating a script to implement a sampling scheme that would basically make it more likely that a particular observation is chosen based on a weight associated with the observation. I am trying to select a sample of ~30 census blocks from each ZIP code area based on the proportion of women in a ZCTA living in a particular block. I want to make it more likely that a block will

Dear all: I have two larges files with 2000 columns. For each file I am performing a loop to extract the "i"th element of each file and create a data frame with both "i"th elements in order to perform further analysis. I am not extracting all the "i"th elements but only certain which I am indicating on a vector called "d". See an example of my code below

Is there any package that I could use for zipcode search. I want to display schools that near a particular zipcode. I have no idea how to do this.

Hi All, I have a problem with reading in multiple text files where some of the files have no data and was hoping someone may be able to help me find a solution. Each text file is a daily log of fish movement. However, on some occasions no movements will be recorded on a particular day and therefore the text file for that day is empty. I'm currently using the following code to read the

I need to write a method for calculating the fee for medical procedures with respect to area. I have all the tables and data but its hard to give that here. Can someone take a look at this ''stub'' method and help me out? def calculate_fee # strip out the first 3 numbers of the user entered zip code # use those 3 numbers to identify row in [zipcodes table] (between upper and

This is a stupid question I know, but it is driving me crazy - I am missing something simple and basic here. I am trying to update missing zip codes on a data table. I am doing something incorrectly as the data in the Source table is not being updated, only the value in the array is changed. How do I get this to update the actual DB record instead? def add_missing_zips #find all records in

I am new to R. I thing this will be simple, but I don't yet know my way around. I am generating character strings from the system clock that represent integers, and I want to convert them to integer values. Strtoi works well, except when there are leading zeros on the string. Could anyone suggest a way to remove those leading zeros? Thanks Paul -- E. Paul Wileyto, Ph.D.

Dear All, This question sounds very simple but I don't know where I am wrong. I just want to pad leading zeros in some string, for example, "123" becomes "00123". What is wrong if I do following? > sprintf("%05s", "123") [1] " 123" It didn't return "00123", instead it padded with 'blank'. Thank you for your help

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? I need to do some "within 5 miles" calculations of zipcodes and i dont have a nice ruby (or gem) utility to do it. any help would be appreciated. thanks adam _______________________________________________ Rails mailing list

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
