similar to: has_many with :uniq not working for me

could anyone by chance give me a working example of the .uniq! method? i''ve been trying all day. any help would be much appreciated! jon -- Posted via http://www.ruby-forum.com/.

Is there an R analog of the Unix command uniq -c: http://en.wikipedia.org/wiki/Uniq Given an array x, uniq -c replaces each contiguous subsequence of identical numbers with a tuple (count, number). E.g. $ cat > usample 10 10 9 8 8 7 7 7 6 3 1 1 1 0 $ uniq -c usample 2 10 1 9 2 8 3 7 1 6 1 3 3 1 1 0 Cheers, Alexy

Hello *Gem* experts, Sorry for asking multiple questions in one post but they are both related to one problem. So far I have the following code: class Member < ActiveRecord::Base has_and_belongs_to_many :blogs, :uniq=>true ..... end class Blog < ActiveRecord::Base has_and_belongs_to_many :members, :uniq=>true ... end The issue is that

I hope one and all will allow a stats question: When running a cox proportional hazards model ,there are two ways to deal with age, including age as a covariate, or to include age as part of the follow-up time, viz, Age as a covariate: tetest1 <- list(time= c(4, 3,1,1,2,2,3), status=c(1,NA,1,0,1,1,0), age= c(0, 2,1,1,1,0,0),

Hi, I''ve just submitted a patch for ActiveRecord; http://dev.rubyonrails.org/ticket/10463 The patch includes new fixtures because I could not find a applicable combination among the existing fixtures.

This snippet of code pulls an array of hostnames from some log files. It has to parse around 3GB of log files, so I'm keen on making it as efficient as possible. Can you think of any way to optimize this to run faster? HOSTS=() for host in $(grep -h -o "[-\.0-9a-z][-\.0-9a-z]*.com" ${TMPDIR}/* | sort | uniq); do HOSTS+=("$host") done

Hello all, After some months doing ok with R, I am embarrassed that I have to make this my first posting to the help list. I am trying to run the following (actually in a loop but shortened for the post): risk.factors <- c("file$A", "file$B", "file$C", "file$D", "file$E") table(paste(risk.factors[1])) but run into problems

I need an analogue of "uniq -c" for a data frame. xtabs(), although dog slow, would have footed the bill nicely: --8<---------------cut here---------------start------------->8--- > x <- data.frame(a=1:32,b=1:32,c=1:32,d=1:32,e=1:32) > system.time(subset(as.data.frame(xtabs( ~. , x )), Freq != 0 )) user system elapsed 12.788 4.288 17.224 --8<---------------cut

Hi, If i add field observers to radio button fields they trigger once but then nothing after that. I have multiple fields in a form that i need to know if one of them changes and which spedific field. Below is an example of two foelds i tested and they trigger once with the alert but then nothing after that. I also tried individual observers for each field test_yes and test_no but with the same

Didn''t have quite enough space to describe it there...basically i''m having a problem with the :uniq option in my tags. I''m using acts_as_taggable_on_steroid which adds these associations to my Resource class: Resource has_many :taggings, :as => :taggable, :dependent => :destroy, :include => :tag has_many :tags, :through => :taggings, :uniq => true

Getting the through items from a has_many :through :uniq relationship In a nutshell, I have been using the has_many :through :uniq relationship, and I want a DRY way to list the join model objects. Currently, my objects include taxon objects, toxin objects, data_object objects, and taxon_toxin_citation objects ("citation" is another word for data_object). A taxon has many data objects,

Hi I wonder what the state of this ticket is: http://dev.rubyonrails.org/ticket/2019 Does anyone have information regarding whether there are plans to fix this behaviour? It seems strange to me to force uniqueness in Ruby (i.e. application code) but not in the database. For example, in activerecord/lib/active_record/associations/ has_and_belongs_to_many_association.rb there is a line

Hello list, My dovecot setup have expire plugin enabled. It is working fine: new records added to database(sqlite), expire-tool successfully expunges old mail, but when expire-tool try to update database record for processed user, I get error in logs: root at mail dovecot 0:0 # /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh --test Info: koshikov.n at domain.com/Spam:

When SEV is enabled in domcapabilities does that just mean any of SEV, SEV-ES, SEV-SNP is possible on the hardware? Similarly, does enabling SEV as a launchSecurity option in a domainXML mean that whichever SEV is available will be enabled? And if the guest policy has the ES flag set, it will not be created unless ES is enabled? Sorry if these questions don't make sense or are ill-formed.

Hi, here is the first public post of the patch-set to enable Linux to run under SEV-ES enabled hypervisors. The code is mostly feature-complete, but there are still a couple of bugs to fix. Nevertheless, given the size of the patch-set, I think it is about time to ask for initial feedback of the changes that come with it. To better understand the code here is a quick explanation of SEV-ES first.
