similar to: factor() on a double vector

Hi, x <- c(rep(1800000003L, 10000000), -rep(1200000002L, 15000000)) This is correct: > sum(as.double(x)) [1] 0 This is not: > sum(x) [1] 4996000 Returning NA (with a warning) would also be acceptable for the latter. That would make it consistent with cumsum(x): > cumsum(x)[length(x)] [1] NA Warning message: Integer overflow in 'cumsum'; use

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I know this has been asked before, but I can not find it - so my apologies. I want to compile R myself, to optimize it for speed. There is a small section (a few lines actually) in the R-admin manual (Compilation-flags) which states that the LDFLAGS "on recent systems ?'-Bdirect,--hash-style=both,-Wl,-O1'? is recommended". But

Hi, install.packages() seems to be broken in latest R-devel snapshot (2010-07-19 r52561) if you are using an R/R.version$platform-library/x.y directory. > .libPaths() [1] "/home/hpages/R/x86_64-unknown-linux-gnu-library/2.12" [2] "/home/hpages/R-2.12/library" > install.packages("car") Error in sprintf(gettext(fmt, domain = domain), ...) : too

Hi, The cleanup_pkg() function defined the big tools:::.build_packages() function in tools/R/build.R is currently broken. When Makefiles are used cleanup_pkg() doesn't clean anything because of the way system2() is called. For example, the call to Ssystem() on line 304 (Ssystem is a silent version of system2) is basically trying to do this: >

Hi, The following code produces different kinds of problems depending on which platform you run it: x <- as.list(1:200000) names(x) <- paste("A", 1:200000, sep="") e <- list2env(x) Timeout on Linux, crash on Mac and Windows, with R 2.12.0 and current R devel. The "multi-assign" mode (i.e. when the 'envir' arg is supplied) doesn't seem

I get this (with R-2.12 and R-2.13, didn't try with earlier versions): > max(c(NaN, NA)) [1] NA > max(c(NA, NaN)) [1] NaN I get the same thing with min(). The fact that the result of 'max(x)' or 'min(x)' depends on the order of the elements in 'x' is surprising. It also seems to contradict the man page: By definition the min/max of a numeric vector

Hi, According to its man page substring() "expands (its) arguments cyclically to the length of the longest _provided_ none are of zero length". So, as expected, I get an error here: > substring("abcd", first=2L, last=integer(0)) Error in substring("abcd", first = 2L, last = integer(0)) : invalid substring argument(s) But I don't get one here:

by() does not always return a list. In Gabe's example, it returns an integer, thus it is coerced to a list. as.list() means that it should be a VECSXP, not necessarily with "list" in the class attribute.

Dario, What version of R are you using. In my mildly old 3.4.0 installation and in the version of Revel I have lying around (also mildly old...) I don't see the behavior I think you are describing > b = by(1:2, 1:2, identity) > class(as.list(b)) [1] "list" > sessionInfo() R Under development (unstable) (2017-12-19 r73926) Platform: x86_64-apple-darwin15.6.0 (64-bit)

Hi, I'm running into a case where byte-compilation changes the semantic of a function. This is with R 3.4.0: foo <- function(x) { TRUE && x } foo(c(a=FALSE)) # [1] FALSE # OK foo(c(a=TRUE)) # [1] TRUE # OK foo(c(a=FALSE)) # a # ???? # FALSE The 3rd call returned a result that it different from the 1st call! After

Hi, On both Unix and Windows there is a mechanism to add variables to the environment when R is started. I noticed that, on Unix, this mechanism is not used when R is started normally at the command line but only when it's started using the 'R CMD' syntax. One problem with this is some lack of consistent cross-platform behaviour. For example: On Linux: $ echo $TEXINPUTS $

I just meant that the minimal contract for as.list() appears to be that it returns a VECSXP. To the user, we might say that is.list() will always return TRUE. I'm not sure we can expect consistency across methods beyond that, nor is it feasible at this point to match the semantics of the methods package. It deals in "class space" while as.list() deals in "typeof() space".

Hi, Here is a problem we see with the Mac and Windows binaries of rJava (0.9-3) currently available on CRAN for R-devel (i.e. under bin/macosx/leopard/contrib/2.16/ and bin/windows/contrib/2.16/): > library(rJava) > .jinit("gaggle/inst/jars/gaggleRShell.jar") Error in .Call("R_do_new_object", ClassDef, PACKAGE = "base") :

Hi, Already reported here: https://stat.ethz.ch/pipermail/r-devel/2010-September/058636.html but it doesn't seem to be related (at least not in an obvious way) to the problems described in that previous thread. So the problem is that, with recent versions of R 2.12 (i.e. current R-alpha but I've observed this with R-devel for at least 2-3 months now), 'R CMD build
