Dear helpers, I'm working with expression matrices (DNA microarrays) and my professor suggested me to investigate the possibilities of Xgobi. Searching the net I found that I could use it with R. Is that true? How can I do this? I'm working on a Windows ME notebook. I've already got xgobi.zip from CRAN and xgobi.zip from Professor Brian Ripley

Hi again. Thank you for the tips but I don't know what is a X server. I remember that I?m working with my own notebook. Is this possible?

Hello! I need to classify a data set with 19 variables and 9 classes using Logistic Regression(on R). I know that when we have only 2 classes we can use glm() to estimate the coefficients of the model. But I don?t understand how can I do a classification task with Logistic Regression on a data set with 9 classes! Does anybody know how can I estimate these coefficients (of a model with 9

I don't understand where is my problem. I tried the problem suggested by Prof. Brian Ripley data(USAccDeaths, package="ts") and it worked. So this is not a machine or configuration problem.

Hi again With arima0 the problem was solved but what are the diferences between arima and arima0? I have another question. I fit the model to the data and I make some predictions. But I also want to calculate MAPE based in the last 3 observations available. Is it possible? Can I obtain the fitted values from the model? thanks~ luis -- SAPO ADSL.PT, apanhe j? o comboio da Banda Larga. Kit

Hi, I have a microarray matrix 3000x70 for example (genes x experiments). This data has more than 2 classes. I would like to make some filtering on the genes.
