Hi. I tried running the following code. I don't understand the error. mydata <- read.table("C:/dataForR/radiology/wordFrequencies.csv", header=TRUE, sep=",") > dim(mydata) [1] 982 924 mydataN<-mydata[,-923] > dim(mydataN) [1] 982 923 cor(mydataN) factanal(mydataN, factors=3) Error in solve.default(cv) : Lapack routine dgesv: system is exactly singular

Hi Torok, I've used a hard-coded list on the input parameter and still got some output (slightly) scrambled between two different bots... INPUT = $(PROJ_SRC_DIR)/inputs/clam.cab \ $(PROJ_SRC_DIR)/inputs/clamdoc.tar.gz \ $(PROJ_SRC_DIR)/inputs/clam.exe \ $(PROJ_SRC_DIR)/inputs/clam.exe.bz2 \ $(PROJ_SRC_DIR)/inputs/clam-v2.rar \

Hi. I started with a file which was a sparse 982x923 matrix and where the last column was a variable to be predicted. I did principle component analysis on it and arrived at a new 982x923 matrix. Then I ran the code below to get a neural network using nnet and then wanted to get a confusion matrix or at least know how accurate the neural net was. I used the first 22 principle components only for

Hi all, I am trying to construct a pairwise coocurrence matrix for certain terms appearing in a number of documents. For example I have the following table with binary values showing the presence or absence of a certain term in a document: term1 term2 term3 term4 term5 doc1 1 1 0 0 1 doc2 1 1 0 1 1 doc3 1 0 0 0 1 And I want to have a matrix with the number of the pairwise coocurrencies. So,

I thought we needed a new template only for the second log file? To generate the first log file using the existing $log command, I have introduced another $log command in query template that looks like:

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

I'm struggling with package XML to parse a Garmin file (named *.tcx). I wonder if it's form is incomplete, but appreciably reluctant to paste even a shortened version. The output below shows I can get nodes, but an attempt at value of a single node comes up empty (even though there is data there. One question: Has anybody succeeded parsing Garmin .tcx (xml) files? Thanks! Michael

I want to compare two documents in the index (i.e. retrieve the cosine similarity/score between two documents term-vector''s). Is this possible using the standard Ferret functionality? Thanks in advance, Jeroen Bulters -- Posted via http://www.ruby-forum.com/.

Hi, I''m using Rails 2.2.2. I noticed that creating two references to the same database ActiveRecord object, then deleting with one of them, followed by saving with the other, true is returned, but no new record is actually saved. e.g.: doc=Document.new(:title => "sam''s speciality") doc.save doc.id # ==> 23 doc2=Document.find_by_title("sam''s

Hello, Thanks James for the reply. That cleared a few things out. Apologies for replying late because of exams going on. I was going through the previous clustering API to understand how it worked and it seems like the the approach for construction of the termlists which are used for distance metrics use TF-IDF weighting with cosine similarity, which is very similar to the approach I would need

Hello, after having no problem with four Windows 2000 workstations and one Samba 2.something server for several years in a medical practice the practice software (DocComfort) dropped support for Windows 2000 beginning of this year. So I bought new hardware for the workstations and servers and installed from scratch. Now there are four Windows 7 Professional 32bit Workstations (with UAC disabled)

I am looking to have a number of categories populated from my results of a search. For example, searching on "sport" would display all results for sport. I want to also have a number of categories to refine the documents down. So by clicking on the "Fishing" category or the "Shooting" category, I would only see the results on sport around that category. Now for
