This bit of code finds several groups; all those which have entity_id''s of ''1'' OR ''2'' OR ''3'', as you would expect: ee = [ 1, 2, 3 ] groups = Group.find(:all, :conditions => "entity_id in (" + ee.join (",") + ")") But this bit of code only finds groups which have entity_id''s of

Hi all, I just finally figured out how to get 2.2.2 to do this, and thought I''d share in case others run into the same thing. The situation is a find with associations, but the tricky part is that the association shouldn''t always be loaded. This is similar to putting a condition on a has_many association in a model, but the condition is dynamic rather than predefined. The

I have two models called entity and user. The entities table has a column called users_id that contains the user id of the user that created the entity. In entity I have... has_one :user ... as I want to be able to show the user who created the entity from the entity object. But this produces the following error... Mysql::Error: #42S22Unknown column ''users.entity_id'' in

When I''m executing cucumber tests, I noticed that sometimes rails app (in test env.) getting several the same requests (GET or POST) usually around 3, and it doesn''t render anything with empty HTTP status code. Have anyone met something similar to that issue? here is some example of log file: Started POST "/account" for 127.0.0.1 at 2010-11-30 22:34:17 +0200

Hi llvmdev, I've noticed that there is no unary operator in LLVM. For unary operator such as Neg or Or operator, the IR builder just creates a binary operation with one dummy operand, 01823 <http://llvm.org/doxygen/classllvm_1_1BinaryOperator.html#a073c092ce74a122e898e435e60e84599> BinaryOperator <http://llvm.org/doxygen/classllvm_1_1BinaryOperator.html>

Hi everyone. What's going on here? > a <- matrix(1:4,2,2) > a [,1] [,2] [1,] 1 3 [2,] 2 4 > apply(a,2,sum) [1] 3 7 > apply(a,2,"+") [,1] [,2] [1,] 1 3 [2,] 2 4 > apply(a,1,"+") [,1] [,2] [1,] 1 2 [2,] 3 4 > help(apply) says that "+" should be quoted but is otherwise silent on unary

Hi all, Why not make the unary minus operator return the factor with levels reversed? This would make it much easier to sort factors in descending order in part of an order statement. Hadley -- http://had.co.nz/

Jim, This seems cool. Thanks for proposing it. To be concrete, he user-defined unary operations would be of the same precedence (or just slightly below?) built-in unary ones? So "100" %identical% %chr% 100 would work and return TRUE under your patch? And with %num% <- as.numeric, then 1 + - %num% "5" would also be legal (though quite ugly imo) and work? Best, ~G On

I don't have a positive or negative opinion on this yet, but I do have a question. If I define both unary and binary operators with the same name (in different frames, presumably), what would happen? Is "a %chr% b" a syntax error if unary %chr% is found first? If both might be found, does "a %chr% %chr% b" mean "%chr%(a, %chr% b)", or is it a syntax error

Hello, Is there a way to define a custom unary operator in R (other than making a class and 'overloading' the normal unary operators in R)? The documentation seems to suggest that only custom binary operators are possible with the ``%abc%``construct but I was wondering whether any one has done so. None of the RSiteSearch or RSeek queries I posed suggested that this question had

Hi guys I have been using R for a few months now and have come across an error that I have been trying to fix for a week or so now.I am trying to build a classifer that will classify the wine dataset using Naive Bayes. My code is as follows library (e1071) wine<- read.csv("C:\\Rproject\\Wine\\wine.csv") split<-sample(nrow(wine), floor(nrow(wine) * 0.5)) wine_training <-

Hello, Is there a way of generating unary floating point operations (like ISD::FABS, ISD::FSIN, ...) from C code using clang? I am building a backend for a machine that has hw support for these ops and I need a way to test them. Thanks, Alex -------------- next part -------------- An HTML attachment was scrubbed... URL:

I am making some changes to the permax library (so that it will accept NA's). This function performs a permutation analysis to identify discriminating attributes distinguishing two groups of observations. It takes the form (at its most simplistic): permax(data, ig1) where ig1 is one group of interest. The other group (if not specified) is assumed to be the remaining observations, namely,

Is it correct (by its lack of mention in the R-Language Definition Manual) that it is impossible to create a user-defined unary operator? Ex: (This doesn't work, but it's an example of what I'm looking for) > "%PLUSONE%" <- function(x) x + 1 > %PLUSONE% 2 [1] 3 And if the above is impossible, am I limited to only the + - ~ ! unary operators for overloading?

Hi Herve, I think you are confusing subclasses and classes. There is no contradiction. `is` documentation is very clear: `With one argument, returns all the super-classes of this object's class.` Note that object class is always `data.frame` here, check: > class(data.frame()) [1] "data.frame" > is(data.frame(), "data.frame") [1] TRUE Best, Mehmet On 29 Nov
