Hello, I will really appreciate some help with the following question. let's say cor.m is a correlation coefficient matrix. tree<-hclust(as.dist(1-cor.m)); plot(tree); my question is: is it possible to add the correlation coefficient information to the plot? thanks, S. Ma

Hi - I use stepAIC to automatically select the model. The stepAIC was applied on polr as follow:objPolr <- polr(formula=myformula, data=dat, method=METHOD);objPolr.step <- stepAIC(objPolr, trace=T);Then R complaints that it doesn't know about 'dat' when it executes the second line. Below is the exact error that I got when executing the stepAIC line above:Error in eval(expr,

I and another person who has successfully used the sem package for similar analysis (fMRI effective connectivity) cannot figure out what is wrong with my code. I would appreciate any suggestions.

To clear up a question regarding my earlier posting regarding random changes in a vector: Say you have a vector (1, -1, -1, 1, 1, -1). I want each value in the vector to have a probability that it will change signs when this vector is regenerated. For example, probability = 50%. When the vector is regenerated, the first value in the vector (1) has a 50% chance of switching to -1. If I

hello everybody I use the following code for my programming & it runs with the error as specified below.Any help that would disolve the error will be highly appreciated.

Hello R and BUGS users, I am writing a heirarchical model in R to send to BUGS via R2WinBUGS and I am finding it difficult to get the model to run. I seem to be having two problems. 1) I can't seem to send variables classed as factors (Month), is there a way do this? 2) Checking the Log in WinBUGS I can see that the model is Syntactically correct, but Bugs is not able to recognise the the
