S Programming by Venables and Ripley (page 78) has the example listed at the end of this email. However, I get the following error when I try the example. I don't understand the descriptions of NextMethod on its help page. Could somebody let me know how to fix the error of this example? > test(x) c1 c2 Error in NextMethod() : no method to invoke Calls: test -> test.c1 -> NextMethod

What does it require to run the example on page 263 of Venables/Ripley book using R 1.3.0? I got the following error and I have no clue how to correct it. Thank you very much. (If you reply to the list, please send a copy to me.) > lmix2 <- deriv3( + ~ -log(p*dnorm((x-u1)/s1)/s1 + (1-p)*dnorm((x-u2)/s2)/s2), + c("p", "u1", "s1", "u2",

Congratulations to Bill Venables and Brian Ripley for their latest "tour de force" - MASS 4, which just arrived in my mailbox last week. As always, the book contains new pearls of wisdom to improve my statistical and programming skills. Kudos also to Peter Dalgaard for his "Introduction to Statistics with R". It is a delightful volume that I can recommend to all those

Hi Are there any functions that de-convolute data into a given number of clusters, rather like the NPMLE GLIM macros from Murray Aitkin and Brian Francis? Basically I would like to code into R the same approach but include the possiblility of some data being censored. In principle the formulae are the same (just replace the likelihood function) but I haven't managed to get my head round the

Hi, first of all: I'm not only new to R, but also to S. I hope this is the right forum for asking the following very stupid questions: a) is there a straightforward way of saying for all factors f in a data frame { any old function, e.g. max(f) } b) how can you construct a new data frame d' from a given data frame d which contains only rows with [X=="A"] (x is

Thanks to all who offered suggestions for my question of how to "remove" row.names. As Bill Venables patiently pointed out, row.names are part of the object-oriented design of the S language (all dialects). As a result, there is no way to "literally" remove row.names and still have a data.frame. This was a useful thing to have Bill point out. In fact, my problem was

Are there any S-Plus or R libraries/packages that do Finite Mixture Analysis following the algorithms similar to those implemented in Geoffrey MacLachlan's EMMIX program? Thanks. Dr. Marc R.

I just downloaded the binaries for the released 1.2.0 for Windows (from Guido Masarotti's site). In using the rwinst.exe installer, I noted two significant problems. First, the installer seems extraordinarily slow compared to the the 1.1.1 installer. It took almost 20 minutes to perform a full base extraction from binaries to installation (all base pages, html help, windows help, pdf

There are two separate problems with loess under Guido's rw0632 on Windows, neither of which appear unless you try to do something that it is trying to tell you is inadvisable. It bombs trying to tell you. I have put up a replacement modreg.zip in the CRAN contrib collection that will be mirrored tonight. Both of these could potentially affect other platforms.

Hi, I just installed FC4 and Wine-20050930 for my sister from this place: http://www.winehq.org/pipermail/wine-devel/2005-October/040702.html http://komi.bluezones.org/wine/fc4/20050930/ Thanks for the compilation, Dieter! My sister's daughter has whined for "Barbie Beauty Styler", so I tried installing it. The installation from the CD root kept complaining about it has to

Dear colleague, I'd like to compute linear discriminant analysis, using R. In the book Modern applied statistic with Splus (Venables & Ripley, p. 396), lda function is used. Could you tell me where I can find this function? At what site, can I download this library ? Thank for your help.

Hello, after searching through the archives and not finding a thread that answers this question, I thought I'd pass it on to the list. Given a data frame and given a factor variable that assigns a class to each case in the data frame, what is the most efficient way to sample a given number of cases from each class? I've found a roundabout solution that works as follows: for each class:

While termplot is under discussion, here's another proposal. I'd like to change the default for partial.resid to TRUE, and for smooth to panel.smooth. I'd be surprised if those changes were to break existing code.
