Consider: > x <- matrix(1:6, 2,3) > rownames(x) <- c("ID1", "ID2") > colnames(x) <- c("Attr1", "Attr2", "Attr3") > x Attr1 Attr2 Attr3 ID1 1 3 5 ID2 2 4 6 > write.csv(x,file="x.csv") "","Attr1","Attr2","Attr3" "ID1",1,3,5

In R-devel (svn 49628) and back to at least R 2.7.0 we get inconsistent results when attempting to attach attributes to a variable with the value NULL. If we use attributes<- it finishes but changes the value to list(). > a<-NULL > attributes(a)<-list(attr1="First attribute", attr2=2+2i) > a list() attr(,"attr1") [1] "First

I would like to replace "\r\n" with "" in a character string, where "\r\n" exists only between < and >, how could I do that? Initial: characterString = "<XML><tag1 id=\"F\r\n2\"></t\r\nag1>\r\n<tag\r\n2></tag2></XML>" Result: characterString = "<XML><tag1

Dear R experts, I would really appreciate if you had an idea on how to use more efficiently the aggregate method: More specifically, I would like to calculate the mean of certain values on a data frame,? grouped by various attributes, and then create a new column in the data frame that will have the corresponding mean for every row. I attach part of my code: matchMean <-

Hi, I have 100000 units with 10 attributes (attr1, attr2, attr3, etc...) For instance: unit attr1 attr2 attr3 ... 1 a ww 12 2 a re 11 3 b ww 09 4 c yt 02 5 a qw 02 ... I'd like to answer to the question: a) what are the most frequent combinations of attributes? b) How could I describe the relations

Ok, So, I''ve got two data tables associated through a foreign key. class Child < ActiveRecord::Base belongs_to :parent, :class => Parent, :foreign_key => "parent_id" # also has attr1, attr2 end class Parent < ActiveRecord::Base has_many :children, :class => Child, :foreign_key => "parent_id" end So, I''m trying to build the new/edit

I find myself writing the following frequently: r = MyActiveRecord.where(:attr1 => cond1, :attr2 => cond2, ...) r.exists? ? r.first : r.create ... which has the effect of returning an instance of MyActiveRecord if all the conditions are met, or creating one if it doesn''t. A variant of this: c = MyActiveRecord.new(:attr1 => val1, :attr2 => val2, ...) r =

Thanks for your feedback David.... Yes, the intention is to support duck-typing. In my code example, a.attrB1 = 5 .... is probably more accurately stated as ..... a. attr1.attrB1 = 5 Certainly this would be an unsafe call because we would not know that attrB1 is an attribute of attr1 until runtime. I believe this type of call is valid in a language like Python. Are there any

Hey...I''m trying to search a Model that uses acts_as_taggable for multiple tags. I''d like to pass in a search string containing a space delimited tags names (i.e. "tag1 tag2") and return the objects that have been tagged by either one of those.

When I use rbind() or rbind.data.frame() to add a row to an existing dataframe, it appears that attributes for the column of type "factor" are dropped. See the sample example below to reproduce the problem. Please suggest How I can fix this. Thanks, Sammy a=c("Male", "Male", "Female", "Male") b=c(1,2,3,4) c=c("great", "bad",

Hi All, I have been learning some ruby and some Camping at the same time by implementing a little webapp to track expenses (one man''s blog...) that includes the ability to tag entries with 1 or more tags. I wanted to offer the possibility to narrow the view of expenses by adding tags to a filter (this works) and I also wanted this filter to be reflected in the URL. Like so: normal URL:

Hi all, I''m working on a Backbone.js single page app with Rails 3.1, and in an attempt to save on HTTP requests, I want to embed initial data set in a HTML document that is sent back to the browser after successful login. I was thinking I can simply convert my ruby object to JSON, then HTML escape resulting string of JSON, and then use that as a value for JavaScript variable. Something

Hello, to implement some some kind of optimistic locking, I want to build a view, where an object is displayed together with a link containing the data of the displayed object. My first try looked something like <%= object.object_discription %> <%= link_to "action", :action => "take_action", :data => object %> this won''t work because object is of

Hello everyone, I would like to implement functionality something like the following in my sample language..... class A { Object attrA1 } class B { int attrB1 bool method methTestB ( .... ) } main () { bool test Object a a = new Class A() a.attr1 = new Class B() a.attrB1 = 5 test = a.methTestB(...) } I assume that I will need: - some type of runtime lookup table to store

Hi, At the code below from ./bindings/ocaml/executionengine/executionengine_ocaml.c, we create an OCaml Variant from C. It is from 2.6, the latest 2.7 has the same code. Line 240 Option = alloc(1, 1) assigns tag1 to the 'some' constructor. In term of http://caml.inria.fr/pub/docs/manual-ocaml/manual032.html, I think the 'some' should have a tag 0. We dont have a runtime error for

Im trying to create an api, and Im having trouble getting ActionController to not run the raw post data through Hash#from_xml (request.parse_formatted_request_parameters) for the XMLRPC post data.
