[Same question for max(.), cummin(.) and cummax(.)] In S, S-plus and R, this currently gives NA. I wonder if it wouldn't make more sense to follow common mathematical/logical reasoning here: min { empty set } = +Inf max { empty set } = -Inf (For integers, these would be INT_MAX and INT_MIN, respectively). Maybe this is a real ``first time'': I am proposing a change which

The reason being a design decision of a while ago that "T" and "F" shouldn't be reserved words in R as they are in S-plus. Hence, T & F are just variables being set to TRUE and FALSE respectively; they *can* be overwritten by the user which is very useful e.g., when you do mydat <- read.table(file, header =TRUE) and the file has variable names "T" or

R 0.63 only ------------ (0.62 does not have the print-tests.Rout.save against which to diff!) I'd be glad if some of you could help us find out some printing/formatting differences of the same R version on different architectures. I have the suspiscion that the new glibc aka libc-6 (Linux), has changed some of the internal printing/formatting code [fprintf ..]. One consequence is that

As some of you know, we have been thinking of allowing the possibility of a CHOICE of the kind of random number generator (=: RNG) to use in R. The current R-release snapshot even has some code in it; however, this will be changed quite a bit. Here is a kind of informal RFC (request for comments / request for criticism / ..): 1a. With the new scheme, we still want that save(..) &

Looking into several different parts of R../src/library/base/R/*.R has led me to the conclusion that quite a bit of code doubling could be saved by using the following two functions whose naming philosophy is derived from that of NROW() & NCOL(): COLNAMES <- function(x) if(is.null(n <- colnames(x))) paste(seq(length=NCOL(x))) else n ROWNAMES <- function(x)

In current versions of R, pretty(333) gives an infinite loop (due to a silent integer overflow in src/appl/pretty.c). I've looked at this problem and also at what S-plus does, (no code there to inspect, just experiments), and then I have fixed pretty.c. I think that it now behaves much more reasonably (both than before and than S / S-plus). The only problem: pretty(.) is not

In R and S, the general idea is that data.frames must have unique row.names (aka dimnames(.)[[1]]). Several observations / problems (in R *and* S !). [Example code at the end] 1) Both in S and R, data.frame(..) (and e.g., also cbind(<data.frame>, ..) which dispatches to data.frame()) silently drops the whole row.names and replaces it by "1" "2" ...

[I think Doug Bates has already alluded to this, somewhere..] In R, data.frame( ... ) does not construct row.names whereas in S, it does: R: > data.frame(x=1:2,y=3:4) x y [1,] 1 3 [2,] 2 4 > row.names(data.frame(x=1:2,y=3:4)) NULL S-plus: > data.frame(x=1:2,y=3:4) x y 1 1 3 2 2 4 > row.names(data.frame(x=1:2,y=3:4)) [1] "1" "2"

In order to run some R examples in S & Splus, I want the gl() function in S. In R, it is gl <- function (n, k, length = n * k, labels = 1:n, ordered = FALSE) factor(rep(rep(1:n, rep(k, n)), length = length), labels = labels, ordered = ordered) Since S's factor() has no "ordered= F" argument, in S we need to call ordered() instead of factor() in the case of

The old factor() wars...... {{maybe don't just report that factor()s are broken by design..}} If ff is a factor, e.g., ff <- as.factor(rep(1:2,3)) f2 <- ff; levels(f2) <- c("Lo","Hi") 1) we don't allow {in R as in S-plus 3.x} arithmetic on factors, i.e. 1 + ff gives an error, and I think most of us believe this is as desired. {{if one
