Dear R-forum, I am looking for a good resource/help on working with POSIXct values and controlling the pretty x-axis labels and tick marks for a data VS time plots. Specifically, I wish to do programming logic which creates different vertical ablines calculations based on the range of times which i am working on. The default plot results are adequate, but I would love to make explicit calls on

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 With these one can build 2.4-beta (AKA 2.3.99.0) with mingw32 (gcc-4.7.0). Note, however, that win32 subdirectory is: 1) Lacking a complete Makefile.am, so it can't be built with autotools. 2) Depends on MFC, and MFC is not provided by any MinGW toolset (and MS' MFC is, most likely, highly incompatible with MinGW). So you only get a console

Hello r-experts, I sure could us a little help. I have an ever updating text file with timestamped data in it. I can reformat in anyway I want if need be but currently I have chosen to make columns of date, time and measuresed value (comma delimeted and with the dates and times in quotes to interpret them as strings). Here is a small section of my text data file:

Hello, I''m using: Ruby 1.8.6, Rails 1.2.3, ferret 0.11.4, acts_as_ferret from svn stable. I''ve had quite a day wrestling with trying to remove the use of stopwords. The problem was that when searching for words like "no" or "the", no results were found. I found a confusing thing behavior that has taken me some time to figure out, and I hope sharing it

hi all: i downloaded libtheora1.0.tar.gz from xiph.org, and when i compile it, such error message popped. i tried to run player_example.c under /libtheora_1.0/examples/. error message: ivysummer at ivysummer-desktop:~/??/libtheora-1.0/examples$ gcc -o player player_example.c /tmp/ccpyle3c.o: In function `buffer_data': player_example.c:(.text+0x15): undefined reference to

Hi My PC is Intel Pentium P4-HT, running Linux kernel 2.6.0-test10. I have the latest GNU automake/autoconf system. The make fails on libtheora with the following error msgs: player_example.c:29:1: warning: "_REENTRANT" redefined player_example.c:1:1: warning: this is the location of the previous definition /bin/sh ../libtool --mode=link gcc -O2 -D_REENTRANT -all-static -o

Hi I've just started development on a streaming TV player using Theora as a real time encoder. The player currently uses the majority of code in src/player_example.c. I discovered a bug which was preventing the player from working correctly, but which only showed up in my player; it didn't seem to affect the original player_example. I've now found the cause, which is indeed a

Speaking of portability and people more familiar with SDL: The reason we have two example players for theora is that monty wrote the original example around the OSS audio interface used on several free unix-like operating systems, which immediately excludes win32 and MacOS, even though it used SDL to display the frames. SDL also has audio support, and is quite widely ported. splayer replaces

I'm interested in ignoring the audio stream in a theora encoded file. My first attempt was to remove the test for vorbis: /* identify the codec: try theora */ if(!theora_p && theora_decode_header(&ti,&tc,&op)>=0){ /* it is theora */ memcpy(&to,&test,sizeof(test)); theora_p=1; }else if(!vorbis_p &&

A copy of this email goes to the list of theora.

Okay, thanks to some stubbornness on my part and helpfulness on the part of people on this mailing list, I got the Ogg Theora alpha compiled up and installed and running. Yesterday, I went to the Prelinger archives (the public-domain video archive at www.archive.com) to find a high-quality original to re-encode as a test. The encoder worked just fine, and playback as well, and I thought I'd

I have tried following the Theora Micro How-to http://www.xiph.org/archives/theora-dev/200209/0092.html I have been able to: * download * compile * encode But decoding/playing does not work.

Hello, I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP. I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip). When I compile player_example.c Visual Studio shows: fatal error

When using the IDCT routines, the C version [ lib/idct.c: oc_idct8x8_c(ogg_int16_t _y[64],int _last_zzi)] in libtheora 1.1.1, the decoded image is garbled. Is it functionally equivalent to the MMX optimized version [lib/x86/mmxidct.c: oc_idct8x8_mmx(ogg_int16_t _y[64],int _last_zzi)] ? I used some of the Theora video files from here: http://wiki.xiph.org/index.php/List_of_Theora_videos for

Quick update - though not mentioned on the mailing lists anywhere until now, it looks like yesterday sometime, someone posted a "test suite" of datafiles to play with on the main page of www.theora.org ...but after all this time, I seem to have developed a problem with my Theora Alpha 1 build. First, somehow there appears to be a "/opt/kde/lib/libartsc.so" that gets added to

I was just looking at http://svn.xiph.org/experimental/derf/theora-exp/README and this is what it says about the encoder, <snip> The encoder is highly experimental. It currently generates valid bitstreams using ALL of the decoder features supported above. However, it is also currently broken, producing pretty horrible quality files with high bitrates. This should be tracked down and
