similar to: dowload.file(method="libcurl") and GET vs. HEAD requests

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

Dear R-user, I would like to apply spatial statistics on some historical data, in particular from 1850 to 1900 by registration district of England and Wales. I have searched in the R-archive, but unsuccessfully. Do you know whether R contains those shape files? Or where would be possible to download and use in R? Thanks in advance, Carlo Giovanni Camarda +++++ This mail has been sent through the

Hello, I'm install R from a package off of https://cran.r-project.org/bin/linux/ubuntu/. The install works fine but it does not support libcurl as indicated by executing "capabilities('libcurl')". As such, I cannot install packages from HTTPS sources. How can I install R from a package with libcurl support? Is this possible or do I need to manually build R from source and

Dear R devel, Is libcurl support required to run R.devel, or is it optional? I'm compiling R.devel on an older Debian machine that only has libcurl version 7.21.0 The R news file says " Sun, 25 Jan 2015 CHANGES IN R-devel NEW FEATURES Optional use of ?libcurl?

What do you have installed as far as libcurl goes? Would you mind listing your packages and greping for libcurl entries. Perhaps I need some libcurl debs installed when I install r-base?

I am utterly stumped. I need libcurl.so.3 for CentOS 6.4. I have Googled everything and I have been going all over the Internet looking for a solution. I give up; I need help. The error message I get when I try to run a program is: error while loading shared libraries: libcurl.so.3: cannot open shared object file: No such file or directory I have: Package libcurl-7.19.7-36.el6_4.i686 already

Dear all, I am trying to upgrade R on Debian 3.16.0-4-amd64, as the default R version is 3.1.1 (2014).

Hi there, I got a question regarding compiling the icecast2-server: When I'm executing the 'sh autogen.sh' command and is checking for libraries, it says that it didn't find the 'libcurl' library, although I have the curl-rpm installed that includes the libcurl (located in /usr/lib). I compiled icecast2 anyway and tried running it. If I try to get the status.xsl

R-devel r69197 returns appropriate errors for the cases below; I know of a few rough edges - ftp error codes are not reported correctly - download.file creates destfile before discovering that http fails, leaving an empty file on disk and am happy to hear of more.

Hi All, I think there is a memory error in the libcurl connection code that typically happens when libcurl reads big chunks of data. This potentially affects all code that use url() with the libcurl download method, which is the default in most builds. In practice it tends to happen more with HTTP/2 and if the connection is wrapped into a gzcon(). macOS Catalina has a libcurl build with HTTP/2

Hi Martin, Indeed it does (and I should have confirmed myself with R-patched and R-devel before posting...) Thanks, and sorry for the noise.
