Dear R users, Does anyone know if it is possible to use multinom to do a polychotomous fit using one categorical and one numeric variable as response. The doc. for multinom states that for formula , response can be K>2 classes. Is this 2 and more, or as I have understood it only greater than 2. I have tried fitting my data, but have only encountered error messages. On another note, Is it

I'm discovering R (very impressive), and didn't find in the docs a simple method for replacing, in a data frame, missing values (NA) with the column's mean (or any other method for reconstructing missing values when needed). Thanks in advance for your help. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hi,everyone, I am studying the generalized additive model and employ the package 'mgcv' developed by professor Wood. However,I can not understand the example listed in check.in function. For example, library(mgcv) set.seed(1) dat <- gamSim(1,n=400,scale=2) ## fit a GAM with quite low `k' b<-gam(y~s(x0,k=6)+s(x1,k=6)+s(x2,k=6)+s(x3,k=6),data=dat) plot(b,pages=1,residuals=TRUE)

Dear R-Help, Has anyone gotten Xgobi to work in conjunction with R on a windows NT platform? About a month ago there was a thread in which Peter Ho gave a set of instructions on how to do it on windows 95. These instructions worked perfectly when I tried to follow them on a windows 95 pc, but didn't when it came to the NT pc on my desk. I'd be very grateful for a set of instructions of

Hi, Firstly, I would like to thank everyone who had replied to my earlier question of using Xgobi with R under windows. After a little messing around with the xgobi.bat file, I can now export data from R into Xgobi running on the free MIX X server. In summary here is the procedure to make Xgobi work under windows for R: 1) Download the Xgobi for windows executables from Brian Ripley's

Hi, What is the correct form for currently citing R and R libraries in published articles? I haven't been able to find this in R FAQ. The only thing I can come up with so far is, R Development Core Team. 1999. R : A language and environment. Should the version of R be included? i.e. Linux, windows? Thanks Peter

Hello all, I'm very satisfied to say that my grip on both R and statistics is showing the first hints of firmness, on a very greenhorn level. I'm faced with a problem that I intend to analyze using ANOVA, and to test my understanding of a primitive, one-way ANOVA I've written the self-contained practice script below. It works as expected. But here's my question: How can I not

Hi all, Has anyone tried to do k-fold cross validation for flexible discriminant analysis ( mda library), for example, using crossval() in bootstrap? The problem is that the function crossval() requires a separate matrix for predictors and another for responses, whereas the function fda(), using the formula argument only. Is there another way of doing k-fold cross validation for functions which

Dear all, I have recently installed R0.63.2. under Win95. and with it a number of contributed packages. The instructions for adding packages was to unzip the files into the "directory rw0632\library. They are then available for use." However, when I tried one of the function below, I got a Error: couldn't find function "cclust".

Dear R users, Firstly, I would like to congratulate the R core team in bringing out R 1.0.0 and all who have helped in developing it. I have been having problems with using se.contrasts and would be pleased if someone help. I have been doing a repeated measures ANOVA using aov using a split plot design for a single variable, color. The aov results were as follows: > summary(aov(CD2~cont +

I have been trying to get Xgobi to work with the function xgobi( ), but I keep on getting the message ""Xgobi requires a filename or some data from stdin" in the DOS-shell. My Xgobi.bat file is : @echo off PATH=c:\windows\ set DISPLAY=195.23.18.11:0.0 set XGOBIDIR=c:/Xgobi3 c:\Xgobi3\xgobi.exe In R I get: > xgobi(D1) C:\RW0642/library/xgobi/scripts/xgobi.bat -vtitle

Hi, I have a question concerning the analysis of some affymetrix chips. I downloaded some of the data from GEO GSE11324 (see below). In doing so I'm stuck after I identified the probesets with significant changes. I have problems in assigning probeset specific gene names as well as getting the genomic coordinates. Furthermore I have no clue how to deal with the fact, that most genes have

Hello, 1.1pre17 does not support Windows XP.  The reason is that InitOnceExecuteOnce is not supported. I believe it is better to take the Windows XP name out of the download link. -rsd -------------- next part -------------- An HTML attachment was scrubbed...

Hello, A nice guy call Jun Shen was helping me out with this, but I require a bit more help. Below is my data set or list called 'test'. I'm trying to calculate the %RSD for each pair of index and keep it in cronological order if you can imagine a 3rd column with 'date' beside index. Result Index 1 0.2901 17 2 0.2928 17 3 0.2913 18 4 0.2893 18 5

Hi, I'm trying to use Robust non-linear regression to fit dose response curves. Maybe I didnt look good enough, but I dind't find robust methods for NON linear regression implemented in R. A method that looked good to me but is unfortunately not (yet) implemented in R is described in http://www.graphpad.com/articles/RobustNonlinearRegression_files/frame.htm

Dear all, i searched for some classification methods and I have no glue if i took the right once. My problem: I have a matrix with 17000 rows and 33 colums (genes and patients). The patients are grouped into 3 diseases. No I want to classify the patients and for sure i want to know which rows are more helpful for the classification than others. I tried SVM and random forest. Do you think this
