Is there any reason why 'attach' is not generic in R? I notice that it is in another system, for example, and I can see some applications if it were so in R. Bill Venables. Bill Venables, CMIS, CSIRO Laboratories...

Has anyone ever suggested making segments() and arrows() generic (as indeed they are in another not dissimilar implementation)? The practical issue with these functions is the need to specify origin and destination using four separate arguments. It would be much...

Oops! Now that I have persuaded to coax my hideous MicroSoft mailer to reveal Ko-Kang's included file I see that he (or she) has provided quite comprehensive information and my tetchiness was somewhat rash. Sorry. In fact, though...

I was looking for an example of complex variables in R. This one is trivial, but rather cute (though World War II aficionados may 'come over all funny'). See if you can guess the image before you try the function...

As John says, the RSS article was actually an Allstat article attributed to John Nelder. The precise www reference is http://www.mailbase.ac.uk/lists/allstat/1998-09/0132.html If you agree with John's philosophy (and on...

I was surprised to see that S3 methods are not found if they only reside in the enclosing environment. E.g.: > tstFn <- local({ + print.tst <- function(x, ...) cat("found it!") + + function(x) print(x) + }) > > z <- "The cat sat on the...

May I suggest that the method as.data.frame.table not have the name "Freq" hardwired as the response name? This is a problem if "Freq" is already the name of a stimulus factor. Here is the existing function: as...
