hello everyone, i'm new to R, so i hope you dont mind a fairly basic R question. we're using R to manipulate the results of SQL queries and create an HTML output. I'm starting with a table that looks essentially like this: Name Field1 Field2 John value1 value2 Jane value3 value4 My table is stored as a dataframe. I'd like to efficiently produce an

I''m new to rspec and looking for way to test a validation I added to a model. The test checks to see that if field1 has a value then field2 must be nil and vice versa. ------------------------------- When I did the rspec_scaffold it generated one test which worked before :each do @valid_attributes = { :field1 = "value for field1" :field2 = "value for

Hi - I have 3 fileds a user can fill out. They can fill out 2 of them or just one of them, for example. fill out these 2 fields: Field1 and Field2 Or fill out this field: Field3 In my model how do I use validates_presence_of for Field1 and Field2 or just Field3. I want to do something like this: validates_presence_of Field1, Field2 OR validates_presence_of Field3 So the user can fill out

I implemented a "reindex" command which simply creates an IndexWriter with :create => true for a prexisting index. The "reindexing" seems to start out ok, with several thousand docs added, then Ferret throws an exception: IO Error occured: couldn''t rename file "index\_0.tmp" to "index\_0.cfs": <File exists> I guess that _0.cfs is held

Hi and thanks for Ferret! I''m wondering if it would be possible to create a Ferret Win32 gem which includes the c performance code pre-compiled for those of us without a C compiler handy ? Zed Shaw seems to have cracked this particular nut with his Mongrel Win32 gem. Alternately, is there a zip of the Win32 .so Ferret needs that I could download and manually install? Kind Regards

I want to add virtual fields in a model. table: field1 field2 I want to add field3 which is field1*2 + field2 I know tihs can be achieved in View, but I want it in model. Then I will pass this model to PagerRenderer to paginate. How to achieve this? thanks -- Posted via http://www.ruby-forum.com/.

Hi, How can I use a substring match as a condition in a subset command? Sth like this: subset(input, field1=="blah1" & field2=="blah2") # but now with substring match in field2 subset(input, field1=="blah1" & field3 *substringmatch* "blah3") I've tried with gsub, but it won't work: subset(input, field1=="blah1" &

Hello, I wanted to parse some information from a text, where fields are tab separated. When I copy the text into an R session (under emacs) like: mystring <- "field1 field2 field3" the tab character is replaced by a single space! For ex, if I type mystring, I get: "field1 field2 field3" The tabs have disappeared!!! I checked with Python that the text I copied was tab

Hi, I just noticed that Ferret seems to convert every field to a string [ruby code appended for those interested], which has thwarted my attempt to format Dates (to "dd/mm/yyyy") and Floats (to "n.nn") for consumption further down the line based on the class of the field stored. I considered pre-formatting Dates and Floats prior to indexing, which would store the field

I believe that I may have found a bug in R. The top code sample gives an error as shown. However, by simply switching which field is initialized first as in the bottom code sample, it works as expected. This gives an error: a <- NULL a[["field1"]] <- 1 a[["field2"]] <- matrix(c(2,1), 1) Error in a[["field2"]] <- matrix(c(2, 1), 1) : more elements

hi all, how are other people passing and accessing ''get'' parameters from their apps? what is the best way to do it? ie: www.example.com/controller/action/id/extra/extra2/ ?? or www.example.com/controller/action/id/~extra/extra2/ or what ever.... are there built in methods for passing and accessing extra parameters? thanks for your suggestions -felix

Hi, I''m building a web server application using Ferret [thanks so much Dave], Mongrel and Camping which works fine servicing one request at a time, but serialises searches if more than one request arrives, so I''d like some advice please about the best way to use multiple readers and one writer. Some background ... query requests which in my case are always read only, arrive via

Hi David, > Deleted documents don''t get deleted until commit is called Ok, but FYI, my experiments show that #commit doesn''t affect #doc_count, even across ruby sessions. On a different note, I''d like to request a variation of #add_document which returns the doc_id of the document added, as opposed to self. I''m trying to track down an issue with a large

Hi, I have a largish index [700MB] which is updated from time to time, requiring me to close and recreate the Ferret::Search::Searcher to use the latest index. My problem is that the first few searches on the new index are slow [by comparison to before the close/recreate], I''m guessing because the new index is being loaded into RAM by my OS and into Ferret as needed. I''m

Hi all, My current project brought forth the snippet below, which modifies in each row of a data frame a certain field depending on another field in the same row. Dealing with data of some 30000 entries this works, but is horribly slow. Can anyone show this newbie how to do this properly (faster ;0)? for (i in 1:nrow(dataframe)){ if

Hello everyone, I've been advised to use merge to extract information from two data.frames with a number of common columns, but I cannot get a grasp on how it sorts the result. With sort=FALSE, I would expect it to give the result back sorted exactly as the input was but it seems it is not always the case, especially when there are repeats in the input. For example: > a =

Hi, I''m confused about managing field boosting ... I have set the :boost for the :name field in my docs to 10, via :boost => 10 Then I performed a search for ''keith'' over all fields via with *:(keith*), expecting a doc with Keith in the :name field to come out on top. But another doc with Keith mentioned in other fields (:comments, :address) scored higher. I

Say I have a csv file, each row contains several fields, one of them are whether the row is success. In history data, I have all the fields including the result of whether it is success. In future data, I only have fields without the result. For example: history data: Field1 Field2 Field3 Field4 ResultField 1231 CA TRUE 443 TRUE 23231 NC TRUE 123 FALSE

Hi everybody, I need to find out all terms (field values) from one of the fields from a set of documents returned by search. In other words, I have indexed documents with two fields. I do search on one field and then want to know all other field''s values from fount documents. How? -- Sergei Serdyuk Red Leaf Software LLC web: http://redleafsoft.com -- Posted via

Hi, I seem to be having trouble updating a doc, ie, deleting then re-adding to the index. The following script demonstrates my issue - I''m sure I''m missing something obvious, but I can''t seem to find the problem. Can someone point out where I am going wrong please ?
