Estimados Hace un tiempo que no uso rvest, corrí un código viejo, anda sin problemas, escribo el nuevo y hay algo que me olvide. Básicamente desde el navegador de internet selecciono el xpath, copio y pego este en R, pero me sale el siguiente error. > text <- Pagina.R %>% + html_nodes(xpath='//*[@id="content"]/p')%>% + html_text() > text character(0) Miré mi código viejo junto con el sitio que funciona, pero le hice una modificación para que ande (algo en el xpath) pero hoy no recuerdo la parte técnica. Básicamente hay una lista y re...

Hola buenos días: Os remito una duda (en un documento word para su mejor expresión) sobre el uso de la libreria rvest. Mi problema es que como no soy informatico me pierdo un poco, he visto los ejemplos que hay colgados y los he seguido, pero el tema es que quiero acceder a los datos del INE, que en ocasiones estan un poco escondidos con menu de selecciones y no se como hacerlo con rvest para

parted fs resize is deprecated. http://savannah.gnu.org/forum/forum.php?forum_id=6837 parted fs move can only move a partition into free space https://www.gnu.org/software/parted/manual/html_node/move.html The thing to do here is use gparted live or Fedora live media and yum/dnf install gparted. It has a move/resize option that will do what the OP wants. Chris Murphy

I'm trying to wget some very specific files off a web page, but some of the paths are relative paths (e.g. ../path/to/file) rather than abosolute (e.g. http://direct/path/to/file ). Obviously, when wget gets to that part, it craps out... Is there a switch in wget (in CentOS 5 - latest wget package) that lets me maintain this session? I tried some of the options here

Hello. I would like to modify printing of help options in order to fix: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69840 I basically split all *_flags.inc options with new lines. Eventually, these string are printed to limit the output to 80 characters: https://www.gnu.org/prep/standards/html_node/Command_002dLine-Interfaces.html That's my first patch request in the project, please advise

I just got this error message from the GNU assembler: Error: alignment too large: 15 assumed Which made me laugh at first. The corresponding input line was: .align 16 Apparently what's going on here is that ".align 16" is ambiguous: on some architectures it means ".balign 16", and on some it means ".p2align 16", which would mean ".balign 65536" if

When I was reviewing this I forgot the slightly ridiculous rules that autoconf uses for --enable/disable vs --with/without: https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Package-Options.html https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/External-Software.html Since this is disabling an intrinsic feature of the software (a plugin) it should use

Josh, Automake 1.10 on OSX is giving me warnings like the following: test/Makefile.am:50: wildcard *.raw: non-POSIX variable name test/Makefile.am:50: (probably a GNU make extension) test/Makefile.am:50: wildcard *.flac: non-POSIX variable name test/Makefile.am:50: (probably a GNU make extension) test/Makefile.am:50: wildcard *.oga: non-POSIX variable name

Hello All, I was struggling with the need of creating flac files over 2GB recently. Both the command line flac and my util using stream encoder returned FLAC__STREAM_ENCODER_CLIENT_ERROR when reaching that point. Finally I made a small change in libFLAC/stream_encoder.c in file_tell_callback_ function. I replaced the ftello call to fgetpos. This seems to work very well under win32. Based on

...?????? However, I don't know what to do with <externalptr>. ????? The "Selectorgadget" vignette with rvest suggested selecting what I wanted on the web page and pasting that as an argument into "html_node".? This led me to try the following: Bftn_nodes <- html_nodes(Bftn, ???

Hi, This morning one of my servers (centos 4.5) refused to boot. The console shows a lopp message grub loading stage2... I've been able to boot from the install CD choosing the rescue option. I can chroot /mnt/sysimage with no problems and even started the services (network, mysql , httpd etc). How can I solve this? I've followed the manual (

Hello Apparently the file llvm/examples/Fibonacci/fibonacci.cpp generate JIT code without explicitly doing any pass (but I suppose that internally, compiler passes are running!) - is there a dissymetry between JIT machine code generation in memory, and C or ELF shared object generation in files? I thought that all these shared a lot of LLVM infrastructure and happen similarily! Also, the

This time it should hopefully work. I tested all 3 combinations: autoconf ./configure [--disable-linuxdisk | --enable-linuxdisk | <nothing> ] make clean && make && make check and they all appear to do the right thing. Rich.

Hi, Martin! You can find pretty nice instructions how to do it via Phabricator here: http://llvm.org/docs/Phabricator.html. -Maxim On 23/02/16 21:30, Xinliang David Li via llvm-dev wrote: > Can you send this patch to llvm-commits ? > > David > > On Tue, Feb 23, 2016 at 1:15 AM, Martin Liška <llvm-dev at lists.llvm.org > <mailto:llvm-dev at lists.llvm.org>> wrote:

All, we recently had a user report an issue associated with utilizing LLVM-MC as the desired assembler in place of GNU’s GAS. They are utilizing a tangled mess of automake scripts to build this respective software package and have decided to manually override the “CCAS” macro to point directly to LLVM-MC (rather than using Clang). Apparently, automake assumes that whatever “compiler” (as it is
