Hi, I'm not anywhere near an expert, but I had successfully used Darkice, TwoLame, and Icast231 to netcast a mp2 stream. If it will help, here is a snip from the related area of my darkice.cfg: [icecast2-1] format = mp2 bitrateMode = cbr bitrate = 384 quality = 1.0 server = 127.0.0.1 port = 32710 password = (duh!) sampleRate =

Consider > summary(1:5) Min. 1st Qu. Median Mean 3rd Qu. Max. 1 2 3 3 4 5 > summary(c(1:5,NA)) Min. 1st Qu. Median Mean 3rd Qu. Max. NA's 1 2 3 3 4 5 1 Wouldn't it be more stringent if "NA's" was also reported in the first case?? Regards S?ren

Hi all: I want to fit a multinomial logit model with VGAM package, however I cannot find a way to check the residuals since residuals(my_model) and resid(my_model) does not work. Any suggestions? Thanks in advance. Alex Brito [[alternative HTML version deleted]]

Please, I??d like to store this sample matrix as a new object. How can I do this ? pulse <- c(67, 67, 68, 68, 68, 69, 69, 69, 69, 69, 70, 70, 70, 70, 71, 71, 72, 72, 73, 74) m <- NULL x <- 0 for (i in 1:5) { x <- sample(pulse,3) m <- mean(x) cat(x,m,"\n") } Thanks, Mauricio

Dear all, I have 2 matrices, one is a 8x3 matrix, called X; the other matrix is a 3x3 indicator matrix with the diagonal element as 0 or 1. when a variable is included in the model, the corresponding diagonal element is 1, otherwise, it is 0. Let A be a set of matrices that contain the possible indicator matrix. e.g., A= [A1, A2, A3], where A1= [1,0,0;0,0,0,0,0,0], A2 =[1,0,0;0,1,0,0,0,0], A3

All, I am trying to include a day of week variable (1-7) in in a regression model. I would like to have the day of week treated as a categorical variable rather than a number the code looks like lm( dep ~ WKDY) I know this is a basic question, but help would be appreciated thanks spencer [[alternative HTML version deleted]]

Hi, I have a matrix with few hundred by a few hundred and want to extract rows, e.g. (0,1,0), or (1.3, 2.4, 4). I made an example: > A = rep(rep(c(0,1),4),2) > B = rep(rep(c(0,1),each=4),2) > C = rep(rep(rep(c(0,1),2),each=2),2) > X = data.frame(A,B,C,rnorm(16)) A B C [1,] 0 0 0 0.72767870 [2,] 1 0 0 -0.09673298 [3,] 0 0 1 0.51192790 [4,] 1 0 1 -1.54350441 [5,] 0 1 0

Dear Rusers, The default behavior in R when performing a regression model with missing values is to exclude any case that contains a missing value? How could i set the bahavior that R deal with missing values? e.g.: exclude cases listwise exclude cases pairwise replace with mean Thanks very much! -- Kind Regards, Zhi Jie,Zhang ,PHD Department of Epidemiology School of Public Health Fudan

R Help: I have read a number of tables into R with identical headings and I would now like to make a single table that has all the data appended under this single heading line. for example: t1 <- read.csv("f1",header=TRUE) t2 <- read.csv("f2",header=TRUE) all <- c(t1,t2) #all is now twice as wide as t1 or t2 with the same number of row!!!! #I need to know how

Hey there, I'm trying to convert some call recordings from asterisk we have in .gsm format to something I can pipe through ffmpeg - wav would be good, mp3 would be amazing! I've been trying playing with sox but I don't seem to be getting too far with 1239101491.30.gsm -ql -r 64000 -t wav 1239101491.30.conv.wav resample as ffmpeg borks at it: tim at freee-meee:~/dmc/call

Hello, Could you kindly point me to some instruction, how to encode demuxed files (.m2v and .mp2) to .ogg (Theora + Vorbis)? I was trying to use ffmpeg2theora, but I don't know, how to put two files to ffmpeg2theora (one audio an one video) and did not found, how to mux them into one file? Exist a way, how to do two pass encoding? I'm using Ubuntu Fiesty Linux. Thank you, Jiri Navratil

Hello How to create plots dynamically with results of several analysis ? I got many outputs from lm fuction like: mp1.lm mp2.lm mp3.lm mp4.lm mp5.lm ... I'd like to make experimental versus predicted response plots of all analysis in a 'for loop': for( i in 1:10){ x11() plot( mp*i*$experimental_response, fitted( mp*i* ) ); abline(0,1) } I tried: paste( 'mp', i,

Dear useRs? I have the following problem! I have a function that calls one or more functions, depending on the input parameters. I am searching for the fastest way to select and execute the selected functions and return their results in a list. The number of possible functions is 10, however usually only 2 are selected (although sometimes more, even all). For examples, if I have function

Greetings all: OK, this is bugging the @#@%* out of me. I know the answer is simple and straightforward but for the life of me I cannot find it in the documentation, in the archives, or in my notes (because I know I've encountered this in the past). My problem is: I have a data frame with columns A, B, C, D, and E. A, B, and E are factors and C and D are numeric. I need a new data frame with

Dear LLVM: I wrote a small testcase and I can compiler and run it with gcc, But with llvm, I got weird error like the following. I really don't know what's going on. Could you explain? Thanks a lot -Jerry Error Message: xli3|csil-suna38|~/mp2|[25]% llvmgcc testcase3.c testcase3.c: In function `init': testcase3.c:5: warning: cast to pointer from integer of different size

I use 2 packages that both implement a S4 plot method, where one package depends on the other (the bioconductor package globaltest which depends on multtest). When the plot method is used from within the package, it seems the default plot method is used, and an error is generated. When the method is invoked from the console, the plot is created correctly. I have reproduced this with 2 small

I'm using the intrinsic llvm.memcpy which I declare at the top of my file: declare void %llvm.memcpy(sbyte*, sbyte*, uint, uint) and then later use as such: call void %llvm.memcpy(sbyte* %t12, sbyte* %t13, uint %t9, uint 0) However when trying to compile the llvm program I get this: cpp -I/home/class/cs326/mp/mp2/lib cgen_test.ll | sed -e"s/#.*//" > cgen_test.bc.exp llvm-as

Jean-Marc, I am building a tool for producing the highest possible quality Internet interviews for "podcasting" applications. The goal is to produce a perfect recording of an interview or conference -- and giving the participants a glitch-free experience is secondary. My approach, therefore, is to build a Windows "wave" file asynchronously by using a streaming
