Hi, I wonder if there is any function which gives the number of times which an element is repeated in the matrix. Let say there is a matrix, I would like to find out how many times number 2 has been repeated in the matrix, or in other words, how many elements of the matrix are equal 2. Thanks for your help, Rostam [[alternative HTML version deleted]]

Hi R users, I am trying to create a matrix, but R has problem with the size of dim, wondering if there is anything that I can do? > a <- diag(147456) Error in array(0, c(n, p)) : 'dim' specifies too large an array Thanks for your help Rostam [[alternative HTML version deleted]]

Hi R users, I would like to create an image using three matrices which contain the values of Red, Green, and Blue of each pixel, i.e. one matrix which has values of red, one which has values of green, and one which has values of blue. The values are between 0 and 1 instead of 0-255. I have obtained the matrices using the getChannels of pixmap library. I wonder if anyone knows how to create the

Hi, I have three matrices, Red, Green and Blue. I would like to produce a matrix which is the combined values of Red, Green and Blue matrices. I know rgb() does the job, but the values are not between 0-255, they are in the following format: "#2C312C" I would like to have the values between 0-255. I wonder if you could tell me what I can do... Thanks for your help, Rostam

Hi, I would like to run a saved script in windows command line. Some command which takes the filename as an argument, and runs it in R. Thanks, Rostam [[alternative HTML version deleted]]

Ok, now we have the mapping of color names to color codes (see below) and conversion to rgb (something like Ben Bolker's function), but how to convert rgb to hsv? Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker Details below Regards Jens etc/colors.big maps 455 names to rgb in S syntax etc/rgb.txt maps 657 names to rgb in C syntax, but unlike colors() it has mixed upper and

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

Hello, I'd like to ask, how to adjust the space between symbol/line and text in a legend. My legend() is build like that legend(xmax-netzdiff/11, # shouldn't matter here ifelse(ydiff>=0, # ymin-6.5*(netzdiff/11), # ymax-netzdiff/11), # c("stehender Stamm","Windwurf",

I'm having some difficulties pxe booting Solaris. So far I have tried the mboot.c32, and the pxegrub shipped with Solaris. At first I had some problems with blksize, but this disapeared when I changed from atftpd to tftpd-hpa. The point at which I'm stuck now is, the kernel and x86.microroot/x86.miniroot is loaded but then VMWare crashes. I might try with real hardware, but I thought

Sorry - this is a bit off topic, but there is almost certainly someone here who will know the answer... Perhaps even a snom employee :) In recent snom firmware releases, the following sequence always causes a call to be sent from line 'n' Receive call on Line 'n' (where n > 1) Press Hold Dial new call The new call originates on Line 'n' In older firmware

Hi masters! I've this Asterisk 1.4.15 running. yesterday I had to change the firewall schema that I had before. I use to have a FW that would be my network FW/Proxy and do the NATs for Asterisk. This FW was receiving too many requests from my LAN and it was making the Asterisk 'cut' the calls or reach very high latency. Yesterday I added a new FW just for this Asterisk. The same

Hello! I finally found a working solution. calling divactrl with the parameter -n [0..20] gives the DID-length means, if you wanna have 123-XXX in digit-wise mode, then call divactrl load -c 1 -n 3 -f ETSI and the card will wait for n digits. regards, Sebastian -----Urspr?ngliche Nachricht----- Von: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com]

Hi R users, I already had post this question under the title of bmp header, there was a mistake in my post. The following is the same post without the mistake. Thanks Rostam I have a xml file. A value of one of the nodes of the xml file is a bmp image encoded in base64. I would like to read this image by R. I think I should do the following steps: 1. Decoding it from base64 to binary. 2.

Hi Everyone, I am stuck with a simple problem. Suppose I have a vector x, and I want to calculate y[i]=3Dx[i+1]-x[i], it is very easy. I just need to write y<-x[2:length(x)]-x[1:length(x)-1]. Now if I know y, and want to know the vector x defined by x[i]=3Dx[i-1]+y[i-1] for all i, how can I do this without a loop? Thanks, Geoffrey PS. Sorry if you see a duplicate message. The previous

Hi all, I have been running Asterisk for years (CVS-HEAD on 2005-08-24) with no problems save a failed harddrive. I have decided to build a new box and have Asterisk 1.6.2.2 playing nicely with mISDN after lots of changes to dialplan syntax etc. I am struggling with SIP trunks to sipgate.co.uk and dualtalk.com. Does anyone have a working examples? When I make an outgoing call I get... [Feb 5
