I am trying to run, in R -Windows95, the example in MASS2, section 17.2. When I run predplot() on cush.lda I get > predplot(cush.lda, "LDA") Error: couldn't find function "max.col" I get the plot OK, but within predict(), it balks on max.col A more general question about using VR. Is there an easy way to use library on VR...

Please forgive if this question has been asked recently in this list. I've scanned some of the recent archives and the FAQ and haven't found the answer to my question. I'm taking a class on Elementary Stats, basic stuff, and I found R while looking for stats programs that run on Linux. The documentation seems to be fairly complete on the functions contained within R, but to be honest,

...{-l} C' (the generalized inverse of C) has a similar form apart from a few row divisors: >fractions(ginverse(contr.helmert(4))) [,1] [,2] [,3] [,4] [1,] -1/2 1/2 0 0 [2,] -1/6 -1/6 1/3 0 [3,] -1/12 -1/12 -1/12 1/4 (ginverse() will be available in S+4.0 and fractions(), now available in the MASS2 library, simply displays numbers in fractional form so that patterns are more obvious). Thus the phi's are identified by requiring that they add to zero, and *alpha_l = (phi_2 - phi_l )/2, *alpha_2 = [phi_3 - (phi_l + phi_2)/2] / 3 &c. When the columns of C are not mutually orthogonal th...

...ygwin bash on any system). Make a shortcut and run from that. Unfortunately rterm will not either, so until that is fixed, `batch' mode only works on Win9x. An update of making packages on win32 will appear shortly. Meanwhile the latest R complements to V&R (http://www.stats.ox.ac.uk/pub/MASS2/compl.shtml) contain more information on using Windows versions, even on installing and making packages. Finally: from the README: Very little testing has been done: please report problems but do not expect quick repairs. All I have done is tested that the libraries load and run one or t...

...mat are crossed and fr is nested in op*meth interaction. op and fr are taken as random. For each batch, only 4 on the total 5 matrices are mesured (oven constraint), and op and meth are constant. I spent time trying every kind of aov models seeming sensible to me, read the according chapters in MASS2 and still didn't succeed writing the formula to obtain the results I expected (e.a. meth tested vs meth*op, mat vs mat*op, etc.). Can someone bring some light to my clouded mind ? Thanks in advance, Y. Brostaux ===================================================================== YVES BRO...

Dear friends. This is again a very simple question, and I hope you will accept it. I have a dataset with variables in columns all with their names. Now I want to add a column indicating simply identity of patients, numbered according to row. There are 34 rows. So I did: >ID <- c(1:34) but was not allowed to >Ptt <- cbind(patients,ID) and was informed that >Error: names attribute

Hi, here's a short summary of all the mails I got concerning the R help system during the last days ... I really want to have all open questions in this list, so if I forgot your most important topic please forgive (and remind me again) ... it's probably only because of lack of time such that I had to compile the list in a hurry ... Ok, here we go: 1) It would be useful to have a button
