I'm trying to install the ordinal package (http://popgen.unimaas.nl/~plindsey/rlibs.html). I downloaded ordinal03.tgz and untarred it. rmutil was previously installed (and appears to work ok.) Then I installed ordinal: [root at localhost ~]# R CMD INSTALL /home/chippy/Download/ordinal * Installing to library '/usr/lib/R/lib...

Hi I would like to analyse an ordinal categorical variable. I know how I can analyse a nominal categorical variable (with multinom or if there are only two levels with glm). Does somebody know which command I need in R to analyse an ordinal categorical variable? I want to describe the variable y with the variables x1,x2,x3 and x4....

Ping ? Do you think that we need to have an API in LinkingContext to return the next ordinal available, so that files created by passes can be assigned ordinals ?

I''m trying to use the ordinalize() method to ordinalize a day. Here''s how far I''ve gotten: @reportday = Time.now.at_beginning_of_week.strftime("%d").to_i @ordinalized_reportday = "#{@reportday}".ordinalize I was thinking it wasn''t working because the date is being returned as...

Hello I've been asked to help evaluate a vegetation data set, specifically to examine it for community similarity. The initial problem I see is that the data is ordinal. At best this only captures a relative ranking of abundance and ordinal ranks are assigned after data collection. I've been trying to find a procedure in R that can handle ordinal based classification and so far have not found one. Does one exist ? If there is one, which package suppor...

Hi, I am working on a regression tree in Rpart that uses a continuous response variable that is ordered. I read a previous response by Pfr. Ripley to a inquiry regarding the ability of rpart to handle ordinal responses in 2003. At that time rpart was unable to implement an algorithm to handle ordinal responses. Has there been any effort to rectify this in recent years? Thanks! Stacey On Mon, 2 Jun 2003, Andreas Christmann wrote: > >>> 1. RE: Ordinal data - Regression Trees & Pro...

Hi. First of all, excuse me if I do any mistakes, but English is not a language I use very often. I have a data frame with numbers. A small part of the data frame is this: nominal ordinal 2 2 2 1 2 1 2 2 So, I want to use the gower distance function on these numbers. Here ( http://rgm2.lab.nig.ac.jp/RGM2/R_man-2.9.0/library/StatMatch/man/gower.dist.html) says that in order to use gower.dist, all nominal variables must be of cl...

I'm finally cleaning up old things / todo's; We had about half a dozen e-mails on R-devel back in mid March...... Here is my proposal, a sometimes useful utility for constructing strings in cat() or text(), legend(), etc.: ordinal <- function(i, language =3D "english", gender =3D c("female","male"), sep=3D""= ) { ii <- i if(!is.numeric(i) || any(i < 0) || any(ii !=3D (i <- as.integer(i)))) stop("'i' must be non-negative integer") ilang...

After working on some more plugins I realized that the naming for flac's ordinal types were not going to cut it. There is too much chance for conflicts with other libraries/programs with names like 'bool' and 'uint32' so I went back and prefixed all flac ordinal types with 'FLAC__'. It makes the code a little harder to read until you get used to it b...

...ich is not data I'm that used to dealing with. I'm hoping that I can make use of the nabble expertise (again). The questionnaire has a section which contains a particular issue and then questions which are related to this issue (and potentially to each other): 1) importance of the issue (7 ordinal categories from -3 to +3) 2) impact of the impact (7 ordinal categroies from -3 to +3) 3) percentage affected by the issue (11 ordinal categories from 0, 0-10, 20-30, 30-40.....90-100) I also have three participant predictive factors: Gender (M/F) Age (continuous scale) Sector (6 nominal catego...

Dear R specialists, I have a multivariate statistics question that I want to submit to the R community (which conveys a very good statistical knowledge). I need to perform an optimal scaling based on a discrete variable and an ordinal variable. The discrete variable, Area, defines a geographical area. The ordinal variable, EducationLevel, describes the education level of individuals (the ordinal factors are "VeryLow", "Low, "Medium", "Large", "VeryLarge"). I have a data set spec...

...igure out. I have a set of proportion data (from 0-1, rows sum to 1) that I apply metaMDS to using the command: nMDS.set=metaMDS(sqrt(test.set),distance="euclidean",k=3,zerodist="add",autotransform=FALSE) I am using a squared-chord distance metric here. It gives me a great ordination that appears to represent my ecological gradients well. What I want to do is passively add new points to the ordination in an effort to "predict" visually certain ecological attributes. I have tried adding the new points passively using matrix multiplication: passive.points=sqrt...

Hi, It looks like the the ELFPassFile doesnot get an ordinal value assigned, as its added in a pass. Is there a way to assign a file ordinal for the files added by Passes ? Till that time, I am going to XFAIL the ifunc test. More tests should fail, and am not sure why they are not failing. Thanks Shankar Easwaran -- Qualcomm Innovation Center, Inc....

Dear All, I am using a Procrustes analysis to compare two NMDS ordinations for the same set of sites. One ordination is based on fish data, the other is based on invertebrate data. Ordinations were derived using metaMDS() from the {vegan} library as follows: fish.mds<-metaMDS(fish.data, distance="bray", k=3, trymax=100, wascores=TRUE, trace=TRUE, zero=...

Dear Peter.

Hi there, during my work I have to use kernel smoothing methods for multivariate ordinal data. The R-package "KernSmooth" unfortunately includes only a version for continous scaled variables. Does anybody know whether there exists also a version for ordinal data? Thanks for help! --

Dear colleagues, i am carrying out an ordinal regression model. I try it on SPSS but I "flirt" with R as well. I have a few questions. 1. What is the most reliable/tested/trusted package for ordinal regression in the R world? 2. Also, I have a statistical question. What is the danger of having to many 'empty cells' in or...

I have several of these ordinations to perform on different variables (BA, density, RIV, cover, etc..., all in different matrices). I'm running NMDS (metaMDS) ordinations on each matrices, and producing ordination graphs for each cloud of points. The problem I have is that I cannot devise a way to split the cloud of point...
