search path question
...a function that can simply add "C:\inFiles\" into R's search path, so that we I scan a file R will go to all the search paths to find it. In matlab, path(path,"C:\inFiles") will do this job, I'm just wondering if there is a similar function in R can do this job. Thanks, zhiliang [[alternative HTML version deleted]]

enumerates all possible combinations
Hi all R users, I want to create a matrix having n columns and 2^n rows, and all its entries are only 0 or 1. In each row, column i is 0 means dimension i is chosen, 0 means not. The matrix will contains all the possible combination of those n dimensions. Here is an example, if n = 3, the matrix will look like: 0 0 0 0 0 1 0 1 0 1 0 0 0 1 1 1 0 1 1 1 1 I know I can use n "for" loops

Regression for Rank Order Dependent Variable
...However, these are not four independent observations per person, because if a respondent assigned the values to the first three objects, then the rank of the fourth object is pre-determined. Does anyone know if there is a package that can fit a more appropriate model such as the Sin‐Ho Jung and  Zhiliang Ying (2003) "Rank‐based regression with repeated measurements data", Biometrica, 90 (3), 732-740. Any other ideas will be well received. Thank you   Dr. Iasonas Lamprianou Department of Social and Political Sciences University of Cyprus [[alternative HTML version deleted]]

Two-way ANOVA gives different results using anova(lm()) than doing it by hand
Hey! Could you please take a quick look at what I have done? Somehow I get wrong results using the anova(lm()) combination compared to doing a two way ANOVA by hand. Running: Data<-read.table("Data.txt"); g<-lm(ExM~S1*S2,Data); anova(g); Gives: Analysis of Variance Table Response: ExM Df Sum Sq Mean Sq F value Pr(>F) S1 1 4.3679
