i know that title sounds confusing, but here is the deal: the two columns that we are concerned with for this question are the "updated_on" column and the "views" column. the views column increases everytime a user visits a certain page. like this: @object.update_attributes(:views => @object.views + 1) the problem is that when a user visits the page, it AUTOMATICALLY

Hi, I had another question. If you had say a vector (e.g., called data) with 235 elements and each element looked like the following data[[1]] Column A-B Column Z-S Column A-S.... 1 2 5 ....... data[[2]] Column Z-B Column A-S Column A-B.... 2 1 3 ....... Anyway, each element consists of one row

Dear All,   I have a matrix with 33 columns and 5000 rows. I would like to find 2 specific columns in the set: the one that holds the highest values and the one that holds the lowest values. In this case the column's mean would be apropriate to use to try to find those specific columns because each columns mean is different and they all change together based on the same "change of rate

Dear R-Helpers, I have a matrix where the first column is known. The second column is the result of multiplying this first column with a constant "const". The third column is the result of multiplying the second column with "const"..... So far, I did it like this (as a simplified example): nr.of.columns <- 4 myconstant <- 27.5 mymatrix <- matrix(numeric(0), nrow=5,

Hi all. I keep having the following error when I invoke the rake db:migrate command for Rails 1.1 (Ruby 1.8.2 -- Windows 2000) ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate == Realtorex: migrating ======================================================= -- create() rake aborted! undefined method `create'' for

Hello, I'm hoping that there is an easier way to rename columns in a data frame other than by using the names() assignment, which requires you to type in all the column names at once for a data.frame, in the case that I simply want to rename a single column in a data frame. Also, is there an easy way to move columns in a data frame around relative to the other columns? Thanks in

I tried to use ''rake db_schema_dump'' from old MySQL database and then use ''rake db_schema_import'' to rebuild the database in PostgreSQL. The issue here is that only some of tables can be imported successfully. For example, in the dumped schema.rb: create_table "profiles", :force => true do |t| t.column "ticker", :string, :limit

Hi all, I'd appreciate if anyone can help me with this... I have a data frame that looks like this: 1 + name1 1 2 3 2 + name2 5 9 10 2 - name3 56 74 93 1 - name4 65 75 98 I need to rearrange this in a way so that the rows with "1" in the first column, and "-" in the second column; then columns 4 and 6 should switch places. That is, column 6 would be now column 4 and

Dear R forum Suppose I have a data.frame df = data.frame(id = c(1:6), x = c(15, 21, 14, 21, 14, 38), y = c(36, 38, 55, 11, 5, 18), x.1 = c(15, 21, 14, 21, 14, 38), z = c("D", "B", "A", "F", "H", "P")) > df   id  x  y    x.1 z 1  1 15 36  15 D 2  2 21 38  21 B 3  3 14 55  14 A 4  4 21 11  21 F 5  5 14  5  14 H 6  6 38 18  38 P

Dear R users, sorry for a very basic question. i wanted to ask that if your column are too much in number and you want to select the remaining columns, starting from column number 117. one way is to use usual command >q[ ,(117:2300)]. is there a way by which i can select the remaining columns starting from column number 117 without using the usual command or without giving the column number

Hi all .., I have a large dataset of around 600,000 rows and 600 columns. The first col is codes for Meal A, the second columns is codes for Meal B. The third column is customers IDs where each customer had a combination of meals. Each column of the rest columns contains values 0,1,or 2. The dataset is organised in a way so that the first group of customers had similar meals combinations, this

Forgive me if this has been discussed. I''m new to rails and not sure where to check yet. Also... forgive me if this shows up twice. I tried posting first through the google groups interface and I''m not sure if it went through. I have rails 1.2.3 installed. I have a migration that looks like create_table :test_runs do |t| t.column :test_spec_id, :integer t.column

I am sure this is easy but I am not finding a function to do this. I have two columns in a matrix. The first column contains multiple entries of numbers from 1 to 100 (i.e. 10 ones, 8 twos etc.). The second column contains unique numbers. I want to sum the numbers in column two based on the indexed values in column one (e.g. sum of all values in column two associated with the value 1 in column

Dear useRs, I have a matrix with 38 columns and 365 rows. what i want to do is the following..... 1. subtracting from each column, first itself and then all the remaining columns. More precisely, from column number 1, i will first subtract itself(column 1) and then the remaining 37 columns. Afterwards i will take column number 2 and do the same. In this way i want to proceed till 38th column.

I''ve gone once through the Agile book and am now attempting my own rails app. I''ve created a table named ''volunteers'' with over 15 columns. The problem is the default list.rhtml that is created with the scaffold, shows all the columns. I only want to show 4 of them with the list view. Where would I start to only return a handfull of columns to the
