similar to: Prevent attribute from being changed with "attr_readonly"

This will handle all the columns; it assumes the ones you want to start with are in column 2 through the end: > library(dplyr) > df1 <- read.table(text = "ID A B + 1 1 2 + 1 0 3 + 2 5 NA + 2 1 3 + 3 1 4 + 4 NA NA + 4 0 1 + 4

I notice that I always want to prevent the unique key of a table from being changed. Does that mean I always have to have attr_readonly right after validates_uniqueness_of ? Is there a single function that replaces both of these but has the same affect?

I have two tables like: Table A: id (autoincrement) name Table B id id_of_A desc I want to add a record to table A and based on the id of A, I want to add a record to table B. I don''t think there is any SQL command that support this (at least in MySQL 4.1, so I use LAST_INSERT_ID()). (Is there any other way? or MySQL 5 support any special SQL command?) But I need

Hello, my goal is to implement the option of specifying a condition in attr_protected, attr_readonly and possibly other attribute methods in ActiveRecord objects. Rationale (example): class User < AR:Base # User should not be able to modify fields any more once they have been verified attr_readonly :firstname, :lastname, :gender_id, :birthdate, :if => :passport_verified? # ... end

I have gone ahead and implemented the unfold distance option as mentioned in the source. the patch is here http://home.comcast.net/~moppsy/compiz/cube-unfold-distance.patch

Hi I have two data frames as shown below (second one is obtained by aggregating rows of similar IDs in df1.). They both have similar number of columns but rows of df2 are lesser than rows of df1. df1: ID A B 1 1 2 1 0 3 2 5 NA 2 1 3 3 1 4 4 NA NA 4

i'm somehow embarrassed to even ask this, but is there any built-in method for doing this: my_list <- list() my_list[[1]] <- matrix(1:20, ncol = 5) my_list[[2]] <- matrix(20:1, ncol = 5) now, knowing that these matrices are identical in dimension, i'd like to unfold the list to a 2x4x5 (or some other permutation of the dim sizes) array. i know i can initialize the array, then

I was always annoyed that you couldn't terminate an action with dbus so I have written this patch which fixes that. Hopefully this can be included. I wrote the patch trying to repeat as little code as possible so I just added a boolean parameter to the dbusHandleActivateMessage and changed the name to dbusHandleActivateDeactivateMessage. You could probably change the deactivate parameter

Hello, I am looking for a loop unfolding procedure implemented in LLVM that helps to transform a while-loop to n-layer If-statements. The transformation should be on IR, although the example below is illustrated on the source level. original loop: * WHILE (condition) DO action ENDWHILE* Expected unfolded loop (2-layer): * IF (condition) THEN* * action* * IF

Short version: If the integrated assembler accepted assembly strings as input, more targets could take advantage of integrated assembly. The longer version: For a given assembly statement, my out-of-tree target has complex instruction selection logic -- more so than the in-tree targets. This target uses variable length instructions and a laborious hierarchy of tblgen AsmOperands to do the job.

Hi, I have a AR model that I want to limit changes to be only via instance methods that I''ve added. How do I prevent my other sw from setting the instance''s attributes? I know about #attr_protected and #attr_readonly. But the first leaves the individual setters as they were and the second stops all changes. I want something like "attr_private" Thoughts? Thanks,

I am currently running not only Geany (on CentOS and on Windows) but also Gedit on CentOS, much of the use is as markdown-editors being a recent convert to this language. I would, however, also like to be able to essentially use it as an outliner - remember the old DOS outliners that were great for creating document outlines? It would have been perfect had I been able to fold and unfold sections

Hello (and Moin Moin) ;) I have currently a straith Problem ... I have our IMAP-Server migrated from an old cyrus the the current stable Version of dovecot. In the old configuration we organized many mails (e.g. root-Stuff) in Public Folders. They structure had nearly 5 folderlevels. After the complete migration an syncronize we switch complete to the dovecot setup. At this moment we have

Hi LLVM, I have a question that is irrelevant to LLVM developing, but do not know where to post. I found the LLVM webpage uses the following new introduction of LLVM "The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines, ..." I remember the old webpage said that LLVM =

hi all - quick question: i have a matrix 'y' of response values, with two explanatory variables 'x1' and 'x2'. tested values of 'x1' and 'x2' are sitting in two vectors 'x1' and 'x2'. i want to learn model parameters without "unrolling" the matrix of response values. example below: # some fake data for the example x1 <- 1:5 x2

Thank you. Ideally, however, I would like to continue using Geany or gedit. I have found a "gnome outliner" on the 'net but that seems not have been updated for a very long time...

Hi, Recently i have worked on re-writing beryl's transparent cube, and ported 3d plugin to compiz. I'm attaching a patchset here that includes the transparent cube patches (i'll post the 3d plugin when i fix some problems that didn't happen in beryl). Patching order: btf-ftb.patch, clip-planes.patch, plugin-events.patch, cube-paint-order.patch, transparent-cube.patch. Special
