Dear All, I'm preparing a simple algorithm for matrix multiplication for a specific purpose, but I'm getting some unexpected results. If anyone could give a clue, I would really appreciate. Basically what I want to do is a simple matrix multiplication: (WB) %*% t(WB). The WB is in the disk so I compared to approaches: - Load 'WB' using 'read.table' (put it in WB.tmp) and then to the simple matrix multiplication WB.tmp%*%t(WB.tmp) - Scan each row of WB and do the cross products 'sum(WB.i*WB.i)' and 'sum(WB.i*WB.j)',...

I want to read data from a number of files into R. Reading individual files one by one requires writing enormous amount of code that will look something like the following. **************** maptools:::dbf.read("wb-01vc.dbf")->dist1 maptools:::dbf.read("wb-02vc.dbf")->dist2 maptools:::dbf.read("wb-03vc.dbf")->dist3 maptools:::dbf.read("wb-04vc.dbf")->dist4 maptools:::dbf.read("wb-05vc.dbf")->dist5 maptools:::dbf.read("wb-06vc.dbf")->dist...

Muchas gracias a tod en s por las respuetas! tengo en una variable wb una tabla con 145 filas y 17 columnas. dim(wb) 145 17 Creo una variable Serie16, la cual resulta de dividir la columna 3 y la 12. Serie16 <- c(wb[3]/wb[12]) Serie16 Aquí viene el problema. La dimensión de la nueva columna, pensaba que seria 145 filas y 1 columna. Le doy a dim, y me devuelve el...

Hi, Is there any way to determine frame size in bits or bytes of encoded frame in WB mode for given quality? That is I need to know how many bits encoded frame will occupy in RTP packet. I see SPEEX_SUBMODE_BITS_PER_FRAME request, but it works like this only for NB mode, and for WB mode it return size of WB "subframe" (?) only. -- Regards, Alexander Chemeris. SIPez LL...

I haven't tested, but it looks sane. Just a few comments: - printf("\tERROR not enough bits left after wb\n"); this is actually now an error. It just means you got to the end of the frame - I suggest speex_get_num_frames() instead. That works for both narrowband and wideband. Number of samples could be misleading because of nb vs wb frame size. - You can change it to use the nb mode info in mode...

Hi experts, I want to read data from an excel data like this: for the fifth column, from first row until 140 but only 1,3,5,7,.....139 (only 70 values), How can I do it in R? thanks [[alternative HTML version deleted]]

If that's the case, it's *probably* some kind of bug and/or Yes, that's right, except one thing: I always use the blackfin +fixedpoint optimized encoder *and* decoder or the fixedpoint-only optimized encoder *and* decoder at one time....

...'loadURL' is a convenience wrapper which downloads a file, loads it and deletes the downloaded copy. Trying to load an rda file on Windows (XP, R-devel) I was surprised when I received an error about input being corrupted with LF replaced by CR. The fix was to specify mode="wb" to loadURL. This gets passed to download.file and the right thing happens... On unix platforms it doesn't matter whether mode="w" or mode="wb". Will loadURL ever do anything useful on Windows without passing mode="wb"? If not, I think changing the defaul...

I tested that,and the results are: The fixedpoint+blackfin encoder used together with the fixedpoint-only decoder produces an bad sounding file (for all the combinations for quality and complexity I mentioned in my previous postings, and also for both WB and UWB mode).

Hi all, I have a project for the 3G related, AMR and AMR-WB support. I'm using the client develop suite from the PortSIP(http://www.portsip.com), as their said support the AMR, AMR-WB with RFC4867. Now I have to setup a SIP server/SIP PBX in our Lab for test, does the Asterisk support these codecs and RFC4867 ? If no, there has any plugin to support...

I'd like to suggest to change the default of argument 'mode' of download.file() to be mode="wb". The "default" is current mode="w" except when argument 'mode' is missing (not explicitly given), download.file() tries to be helpful by forcing 'mode' to be "wb" for certain filename extensions.
