The problem is that I don't want to have a system service, because I would also need a communication protocol, an arbitration algorithm... I think that there should be an API in logind that would allow a program to block the logout the same than it allows to block shutdown and reboot, and being notified of that. In fact, sometimes I receive a notification in Gnome Shell telling me that

Dear, I am using your ffmpeg2theora for converting VOB files to ogv. At converting VTS_01_2.VOB (second file from DVD) theora can not find video stream, only audio stream. Can you help me? Thanks Martin Koryt?r

We are pleased to announce a new stable release of libtheora, the Xiph.org Foundation's reference implementation of the royalty-free Theora video format. This new release, version 1.1, codenamed Thusnelda, incorporates all of the recent encoder improvements we have been making over the past year, though some of the code had its genesis all the way back in 2003. It also brings substantial speed

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all: I have a question which, maybe, could go to the Theora FAQ. How can I join two theora video files in one without recompressing them? Can I just join them one after the other, like with Ogg/Vorbis? I've created a front-end for Thusnelda and want to offer extra features not yet in other software. My idea is to do multithread compression

Why does the following eval() call on sys.on.exit() not return what I expect/evaluate in the proper environment? foo <- function() { cat("foo()...\n"); on.exit( message("exiting") ) cat("sys.on.exit():\n") res <- sys.on.exit() print(res) cat("eval(sys.on.exit()):\n") expr <- quote(sys.on.exit()) print(expr) res <- eval(expr)

I'm adding things to the Windows RGui so that there's more control of the interface from within R. One thing I'm considering is giving access to the Graphapp window objects using external pointers. This raises the issue of finalization on both sides: - If someone creates a pointer referring to a window, then that pointer should be changed to NULL when the window is closed. - If

(Tried this query on r-help with no luck, maybe someone here can help?) I would like to call the 'RFinalizerEx' function that appears in Rinternals.h using ".Call". It worked for me in the past, but now I get an error message something like: 'call function name not in call table'. I'm using the 1.6.1 rpm from CRAN. Anyone know what's going on? Thanks. Tim --

Hello, I am wondering about the X11() graphic device on Windows. I try to plot a raster image but nothing gets displayed. I found some pages where it is mentioned that x11() not always supports raster rendering. Is there any add on for x11, any update or any R-package which solves that displaying problem in Windows? What I try to test it is an example from the package {raster}: library(raster)

With tryCatch() it is possible to catch interrupts with tryCatch(). Then you can use a 'finally' statement to clean up, release resources etc. However, how can I "protect" against additional interrupts? This is a concern when the hold down Ctrl+C and generates a sequence of interrupts. Example: tryCatch({ cat("Press Ctrl+C...\n"); Sys.sleep(5); }, interrupt =

I have a raster (which I called glc), which I read into R as a raster with "raster.create.from.file" from the raster package (R-forge). Values in glc range between 1 and 27 (whole numbers only). I'd like to extract all cells with a value of 1 to create a new raster with only the cells that have a value of 1, or to extract the xy values of all raster cells with a value of 1. Could you

This code will read binary file and display it as a map. may problem is that this code is using a continuous colour scheme, even though I have discrete data (which is a classification scheme). How can I map numbers to colours with raster? Please require(raster) conne <- file("C:\\lai.bin", "rb") sd<- readBin(conne, integer(), size=1, n=360*720, signed=F)

Hi, str() on raster objects fails for certain dimensions. For example: > str(as.raster(0, nrow=1, ncol=100)) 'raster' chr [1, 1:100] "#000000" "#000000" "#000000" "#000000" ... > str(as.raster(0, nrow=1, ncol=101)) Error in `[.raster`(object, seq_len(max.len)) : subscript out of bounds This seems to do with how str() and

Apologies, I cannot see how to make a rero for this issue. I have a function that uses levels(r) tor return the RAT of a raster "r" when the function is sourced from a script source(".\R\function.r") it works fine. when the function is built into a package and sourced from there library(mypackage) using the same script file to make the package levels(r)[[1]] the same line

Dear R users, I was wondering how I can convert a raster image (that made R through interpolation) into an ascii or csv format? this is the last line of my command p <- interpolate(r, tpsfit) So p is my raster file which I want to convert into ascii or csv Many thanks Regards Mintewab

Hi This is for developers of extension packages that provide extra *graphics devices* for R. In the *development* version of R, support has been added to the graphics engine for sending raster images (bitmaps) to a graphics device. This consists mainly of two new device functions: dev_Raster() and dev_Cap(). The R_GE_version constant (in GraphicsEngine.h) has been bumped up to 6 as a

Hello, I have a large number of raster objects in memory, with names RH100, RH101, RH102, etc. (myobjects <- ls(pattern='^RH')). These rasters are sections of a continuous map, and I would like to combine them using the RasterObject merge tool in package 'raster.' Merge expects an input list of raster objects (outmap<-merge(x, y, ...), where x, y, and ... are raster
