Just a quick followup question: is it true that although manova() performs multivariate two-sample t-tests, it currently does not perform multivariate one-sample t-tests? -S.

Dear Rusers, How would I plot several (24) fitted curves (nonlinear least squares) within a single plot? To get the parameters I use: resff <- list() for (s in levels(PairID)) { resff[[s]] <- nls(Photo ~ SSasymp(Ci, Asym, lrc, c0), subset...
Thanks everyone for your help on this question. I solved the problem by writing a procedure to calculate Hotelling's T^2 for a one-sample, multivariate t-test. Here's how it looks, perhaps it will be useful to...
I would like to test the hypothesis that the difference between pairs, for several variables, is zero. This is easily done separately for each variable with: lm(Y ~ rep(0, nrow(Y))) where Y is a matrix whose columns are...
Hello R users, I can't do demo(graphics) on my Linux box because it aborts after giving me this message on the third plot: Error in title(main = "January Pie Sales", cex.main = 1.8, font.main = 1) : X11...
