Hi, I'd like to perform Dufrene-Legendre Indicator Species Analysis for a multivariate regression tree. However I have problems with arguments of duleg(veg,class,numitr=1000)function. How to obtain a vector of numeric class memberships for samples, or a classification object returned from mvpart? thanks in advance -- Best regards, Agnieszka Strzelczak

Hi everybody, I am doing Indicator species analysis using the function "indval" from the package "labdsv". For further analysis I need the values "Number of Significant Indicators" and "Sum of Indicator Values" that is calculated from the summary on my indval object. indication3<-indval(Veg,caver3,numitr=4999) summary(indication3) cluster

Hello guys I am new to this list and for R too. I am wondering if there is a patch for the SPSS reading code on the foreign package, in order to be able to read long variable names. Right now read.spss() just trunc the names to 8 characters. Or if someone could help me on other way: I have to process everyday a lot of SPSS Syntax Files and Dat files that come from one system that can only export

Hi, I'm working with step.gam in gam package. I'm interested both in spline and lowess functions and when I define all the models that I'm interested in I get something like that: > gam.object.ALC<-gam(X143S~ALC,data=dane,family=binomial) >

I have a question about the function "duleg" in the package "labdsv". How the p-value is calculated ? Dufrene and Legendre (1997) have shown two calculation way ; one is the difference between the observed value and the mean of those obtained from random permutations and another is the rank of the observed value in the randomly generated distribution ordered in decreasing

Colleagues, I have a routine in package labdsv that calls a FORTRAN subroutine. Recently, I was informed that it sometimes gives different results on a PC and Mac, and that the PC version is clearly wrong. I tested it on linux (because I don't have a PC), and I get the same (incorrect) behavior as the PC. Simply by inserting debug WRITE statements in the FORTRAN I would get different,

I am trying to install labdsv from CRAN binaries (or source) to use with R 2.3.0 from Mac OS X, but the package fails to install properly. Here is the message that I receive from R when I type library(labdsv): Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/Library/Frameworks/R.framework/ Resources/library/labdsv/libs/ppc/labdsv.so':

Hi everyone, I am doing PCA with labdsv package. I was trying to create a biplot graphs in order to observe arrows related to my variables. However when I run the script for this graph, the console just keep saying: *Error in nrow(y) : element 1 is empty; the part of the args list of 'dim' being evaluated was: (x)* could please someone tell me what this means? what i am doing

I am trying to install labDSV from http://labdsv.nr.usu.edu/ into R-Windows 1.5.0. It only comes as a TAR file which extracts into folders that seem to match those for other libraries DATA, MAN, R and SRC. I have manually copied these folders into a folder called labDSV under the Library directory under R. However when I load the library I get a message that the library contains no R code.

I have a general question about using thin plate splines in the surf and ordisurf routines. My rudimentary knowledge of a gam is that with each predictive variable there is a different smooth for each one and then they are added together with no real interaction term (because they don't handle this well?). Now, If I have two variables that have a high D^2 score and a low GCV score (I am

I''m trying to find all the unique bill_number, status records in Bills table. I can do it with a find_by_sql statement like this: @records = Bill.find_by_sql( "select distinct bill_number, status from bills group by bill_number, status;") How would I rewrite it using ''find :all

I think I am missing something terribly obvious. Is it possible to have an :expects parameter for a webservice that is an array of objects? I want to have a single webservice that expects all my line items (for an order). Is this something that is possible? -- Posted via http://www.ruby-forum.com/.

Ok, I''m hoping this won''t be a forehead slapper, but take a look at this code: physician.name.sub(/''/, "\\''") I''m trying to substitute a single quote with a backslash and a single quote. This seems pretty simple right? Well, someone kick me and tell me why it''s not :) Here''s what I''m getting if the

Hello, this is a typical "how do you do it in Rails" question :) I would like to incorporate fit testing into a RoR app and I''d like to hear your recommendations on how to do it. In the ideal world I would like all the table test definitions and implementations stored in svn together with the app, ability to run the tests with a rake task + a hook to FitNesse, so that

Hi, I have a strange problem with testing classes which have a HABTM relation. It seems that while running my tests with rake the fixture for the association table is not loaded - as a result I get a failure on a test which simply checks the number of associated elements - it says it''s 0 although there should be one. The weird thing is that when I run the tests with rcov

I tried to use a before_save and use simple_format, it returns and undefined method error. Can I even use these methods within a model? I tried to use auto_link and it failed too. What am I doing wrong? Furthermore, would it be recommended I format text before saving it to the database? Advantages or disadvantages? -- Posted via http://www.ruby-forum.com/.

Hi, I have a problem concerning discrepances between R (which I use) and Statistica (which uses my supervisor). I can't say what is the origin of these differences but unfortunately my supervisor doesn't know that either. Our response variable is number (or presence/absence) of parasites in rodents and explanatory variables are presence/absence of several alleles. The rodents were

Simple question: I know how to access a data field in a hash by doing hash_name[datafield_name]. But what if the datafield itself is a hash? I tried a couple of variations but nothing seems to be working and tutorials do not go into such details. Is there a simple way or should I create separate instances? -Chris -- Posted via http://www.ruby-forum.com/.
