Just now I again had occasion to want nested describe lists in a documentation file. I found that the bug which I reported on 18 October, 2001 still persists. I checked on the bug report at the R web page, and found that the notes say ``Not a problem in R 1.4.0 (2001-12-08)''. Well, it's still a problem for me --- using R 1.4.1.

This is a cry for help. My apologies for taking up bandwidth with an issue that is not really on topic. But I really do want to acquire the requested information. In the course of preparing my PBRF (performance based research funds) portfolio for the upcoming PBRF exercise here in New Zealand, I have been advised that I should provide some estimate of the number of "active users" of

I recently tried to install the latest version of spatstat, from CRAN, using the install.packages() function. It proceeded to install version 1.17-5 of spatstat, although the current version is 1.18-4.

I am trying to construct a function to which I pass an expression as an argument. >From that expression I want to create a somewhat more complicated expression and then differentiate it using D() or deriv(). To give a simple example, I'd like to be able to do something like e1 <- expression(x^2 + y^2) e2 <- some.magic(e1,"n") or maybe e2 <- some.magic(e1,expression(n))

I am (desperately) trying to get used to using a Mac here at my new location. (Why *anyone* would ever use anything other than Linux, except under duress as I am, totally escapes me, but that's another story.) Fortunately much of the Mac OSX is actually Unix, so a civilized person can manage to carry on ... But there are some things. (Like this <expletive deleted> mailer ... But

Hi R People: I am looking at the Braun/Murdoch book, " A First Course in Statistical Programming in R", and I have a question about a function there. It's on page 52, Example 4.5; the sieve of Erastosthenes. There is a line: primes <- c() Is there a difference between using that and primes <- NULL please? When you put in primes <- c(), primes comes back as NULL. Is

I have several hundred Excel 2007 data files in a folder. I would like to read every file in a single given folder using a loop.

I hope someone here can help. I understand that the most common

Dear R People: I ran an ARIMA(1,0,1) on a particular series in R and got a negative MA(1) estimate. Then I ran an ARIMA(1,0,1) on the same series in Minitab and got a positive MA(1) estimate. The values are about -0.69 and 0.70. Does R show the opposite value, please? Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston -
