Dear all, let suppose I have following vector:   > dat1 <- c(rep("asd", 5), rep("xyz", 12), rep("erd", 17)) > dat1 <- dat1[sample(1:length(dat1), length(dat1), replace=F)] > dat1  [1] "erd" "xyz" "erd" "asd" "asd" "erd" "xyz" "asd" "erd" "erd"

I'm also having trouble installing R 1.3.1 on Solaris and getting png and jpeg support. It looks like perhaps the png and jpeg libraries I installed weren't built with all the support R needs. If that's the case I'd appreciate confirmation. Or perhaps there's something else I can do? (with all the details I've included this message is rather long) Thanks -Don I did

I have built R 1.5.0, and tcl and tk 8.3.4 from sources on a Solaris 2.7 machine. All _appear_ to build successfully. tcl and tk pass their test suites. They were configured to build shared libraries (though I also tried it with tk not shared). When I try to use tcltk, I get this error message: > library(tcltk) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to

I''ve written a simple Rails migration that adds an index to an existing Postgres table: class AddIndexToEvents < ActiveRecord::Migration > def change > add_index :sf_events, :account_id > end > end However, when I run the migration, it fails due to a syntax error on the CREATE INDEX line. I''m expecting some SQL like this to be generated: CREATE INDEX

Hi, I'm trying to use StatEt IDE for Eclipse as my R editor, but I'm completely lost. I've read all I could find online, made apparently all I had to do (installing rj, configuraing StatEt, etc.) but still cannot make R running. Below is the error log file. Thank you so much for assistance. Matteo !ENTRY de.walware.statet.r.console.ui 1 0 2011-12-05 16:21:51.355 !MESSAGE

When I create a child record I''m not automagically getting the parent ID put into the fk field. Does object.new take parameters that allows me to do that as part of the AR record creation? Or do I need to do it separately? Or am I missing the boat altogether ;-) Thanks, Bill -------------- next part -------------- An HTML attachment was scrubbed... URL:

I suspect this is a bug. Or a limitation. Problem: ---------------- When you include a STI class in a ''find'' : @results = Result.find :all, :include => :event , you are forced to specify the fk and the class name : belongs_to :event , :class_name => "Event", :foreign_key => "event_id" . Full code: ----------- class Event <

Hello folks, I use to think that a relational databases without foreign keys constraints enforced strictly by the RDBMS were no good, piece of crap, data junk. However, I''ve also learned the hard way that FKs constraints imposes serious difficulties when moving data around, specially between different DBs, or for loading test data or for upgrading DBs schemas, or for porting DBs

Hi folks, I''m wondering if it''s possible to use foreign key constraints on the join tables of a has_and_belongs_to_many relation. Specifically, I get this error when I try and delete a model I''m using, named saved_search, which is many-to-many with neighborhoods. Any ideas? Thanks for any help. :-) -Eric Code: @saved_search.destroy Error: Mupdate or delete on

Hi all.

Hi All! Is anyone working with Oracle on Rails? What about testing? I will be very happy if you can help me: 1) When I run rake test:unit it removes all my sequences in test enviroment.

Hi, I''m a real newbie both in Rails and Ubuntu but I''m going to learn Ruby on Rails for a schoolproject.

Hi everyone! I have a problem with defining 2 fk referencing the same table. I have a Program table and a Team table. The Program should have an away team and a home team fk. From my understanding, "the fk column should be named after the class of the target table, converted to lowercase, with _id appended". But, in my case, I have 2 fk referencing the same table. How can I do this?
