Thanks for looking into it. Is there a way to avoid the HEAD request in R 3.3.0? I'm asking because if there isn't, then I'll add a workaround in a package I'm working on. -Winston On Tue, Jun 21, 2016 at 9:45 PM, Martin Morgan <martin.morgan at roswellpark.org> wrote: > On 06/21/2016 09:35 PM, Winston Chang wrote: >> >> In R 3.2.4, if you ran download.file(method="libcurl"), it issues a >> HTTP GET request for the file.

I see as below, where getGeneric and getMethod imply a different signature; the signature is mode="any" for both cases in R version 3.2.3 Patched (2016-01-28 r70038)I don't know how to reproduce Jeff's error, though. > library(Matrix) > as.vector function (x, mode = "any") .Internal(as.vector(x, mode)) <bytecode: 0xe79f88> <environment:

Dear all, I have come across a strange behavior of the %/% operator, and I wasn't sure if this was intended. i.e. a <- 1.2 b <- 1.0 (a-b) %/% 0.1 results in 1? Whereas 0.2 %/% 0.1 results in 2. Am I missing something obvious here? It seems to be consistent up to R 2.6.0 running in WinXP (haven't upgraded yet). Best, Ken This email message may contain

...setUnion, and so this was an easy switch. I had assumed that since inheriting from a class without slots would produce a class without slots the result would still be virtual. Fortunately that's not the case.

In R 3.2.4, if you ran download.file(method="libcurl"), it issues a HTTP GET request for the file. However, in R 3.3.0, it issues a HTTP HEAD request first, and then a GET requet. This can result in problems when the web server gives an error for a HEAD request, even if the file is available with a GET request. Is it possible to tell download.file to simply send a GET request, without

Hi Luke, Thank you for your response. On 6/21/19 10:56 AM, Tierney, Luke wrote: Thanks for the suggestion. However I don't think it is the right way to go. I also don't care for what install.packages() does. Signaling a warning and then an error means someone has to catch both the error and the warning, or suppress the warning, in order to handle the error programmatically. I do care
