Dear all I would like to have some data in the form of a 2-dimensional array (matrix) of lists, so that I can easily find the desired list object by indexing the structure by rows and columns. In matlab...
Dear R list I am looking for a function in R that computes the integration of a discrete curve, such as a power spectrum, in a specified interval (in my case, that would be 'power in a certain frequency band...
Hi all I am running a 2-way repeated measure anova with 1 between-subjects factor (Group=treatment, control), and 1 within-subject factor (Time of measurement: time1, time2). I extract the results of the anova with: summary(aov(effect...

Dear R users I have a really simple question (hoping for a really simple answer :-): Having estimated the spectral density of a time series "x" (heart rate data) with: x.pgram <- spectrum(x,method="pgram") I would like to compute...
Dear all, I have a BIG dissimilarity matrix (around one thousand by one thousand), that I would like to cluster. Most of the elements of the matrix are zero or close to zero. Is there a way to cluster the...

Dear Thilo, many thanks for your reply. I realized that there was an error in my formula which should have been: aov(y ~ Group * (Time + Age) + Error (Subj/Time), data=df1) or alternatively: lme(RVP.A ~ Group*(Time+Age), random...
Dear all, First of all I apologize if you received this twice: I was checking the archive and I noticed that the text was scrubbed from the message, probably due to some setting in my e-mail program. I am...
Dear all, I am having quite a hard time in trying to figure out how to correctly spell out a model in R (a repeated-measures anova with a within-subject covariate, I guess). Even though I have read in...
