Re: [Rd] for in r-devel

Thanks for pointing this out. The commit you cite was reverted a couple days later, because we are still thinking about how it should work. While it appears Date would benefit, weird things happen e.g. with POSIXlt and other data structures in the wild. This is due to inconsistency in the behaviors

Is the phrase "index <- match(x, sort(unique(x)))" reliable, in the sense that it will never return NA? Context: Calculation of survival curves involves the concept of unique death times. I've had reported cases in the past where survfit failed, and it was due to the fact that two "differ by

Hi, Short story --- setClassUnion("ArrayLike", "array") showClass("ArrayLike") # no slot setClass("MyArrayLikeConcreteSubclass", contains="ArrayLike", representation(stuff="ANY") ) showClass("MyArrayLikeConcreteSubclass") # 2 slots!! That doesn't seem right. L

Re: [Rd] match and unique

Herve, Thank you for the insightful response. It led to the following check: set.seed(1953) # a good year... x <- runif(5e6) ux <- sort(unique(x)) length(ux) [1] 4997142 table(is.na(match(x, ux)) FALSE 500 index1 <- match(x, ux) index2 <- findInterval(x, ux) all.equal(index1, ind

Is it intended that in yesterday's version of R-devel the default value of keepNA is different in nchar (NA) and nzchar (FALSE)? > args(nchar) function (x, type = "chars", allowNA = FALSE, keepNA = NA) NULL > args(nzchar) function (x, keepNA = FALSE) NULL Is it intended that for keepN
