Hello, I was wondering if anyone could please help me with some simple questions regarding ANCOVA and the assumption of homogeneity of slopes. The standard design of ANCOVA assumes the homogeneity of regression coefficients of the different groups. This assumption can be tested using the factor ?? covariate interaction, which should subsequently be removed. However if this assumption is not

I want use survfit() and basehaz() inside a function, but it doesn't work. Could you take a look at this problem. Thanks for your help. Following is my codes: library(survival) n <- 50 # total sample size nclust <- 5 # number of clusters clusters <- rep(1:nclust,each=n/nclust) beta0 <- c(1,2) set.seed(13) #generate phmm data set Z <- cbind(Z1=sample(0:1,n,replace=TRUE),

Can anyone help me resolve this? A part of the R function looks like this: print(is.loaded('merge_xtabs_patterns_file')) print(is.loaded('merge_xtabs_patterns_file_')) .Fortran('merge_xtabs_patterns_file_',ydim[1],ydim[2],x=as.integer(as.matrix(y)),na=as.integer(c), maxD=as.integer(maxD),lrowmem=length(rowmem),rowmem=as.integer(rowmem),

Dear useRs, There is a new version 0.1-2 of the package surv2sample available on CRAN. Users of the previous versions should update because a bug in the function cif2.ks has been fixed. General information about the package: surv2sample provides various two-sample tests for right-censored survival data. Three main areas and corresponding methods are: * comparison of two survival

K-means recluster data with given cluster centers Dear R user, I have several large data sets. Over time additional new data sets will be created. I want to cluster all the data in a similar/ identical way with the k-means algorithm. With the first data set I will find my cluster centers and save the cluster centers to a file [1]. This first data set is huge, it is guarantied that cluster

Hi, in quite a few programs i can not browse the filesystem when opening a "listbox"; to be more clear: for example when i do in winword Open and the listbox appears, and i try to open the pull down menu winword just quits(without an error message in wine). In another program like "Camel join" it quits as soon as i go up to the level of "my computer" with a message

Hi ! Does anyone managed to send multipage faxes (in single TIFF file) with app_txfax from spandsp package (i'm using 0.0.2pre18, libtiff 3.7.1)? If so, I'm interested in format of TIFF file that has been sent sent succesfully (tiffinfo <fax-filename>). I'm having problems with app_txfax, sending first page successfuly 99 % of the time, but never managed to send second or

We will only be doing [A]YUV ordered planar encoding, no other order, not packed using one of several methods.

This is the general outline of my code:: main(argc,argv){ ... Rf_initEmbeddedR(argc,argv); ...

Hi, I'm wondering how I can make my patched up mplayer work with other MPlayer frontends, such as mplayer-plugin, GMPlayer, SMPlayer and KMPlayer. When I play a video using mplayer normally with: mplayer video.ext, It detects the compiz video output and works fine, however when it is called from other players (AFAIK, it just creates a window then asks mplayer to display in it) with mplayer

Greetings, I apologize if I posted this in the wrong list, I wasn't sure where to post it, but seeing as the tags are called "vorbis comments" I thought vorbis, rather than ogg-dev, would be the right choice. (actually, I'm not even a developer anyway) What I'd like to propose is a simple way to encode ambisonic files in vorbis comments as simple tags. By this I don't

hi all, i tried to encode a .yuv file with the encoder_example.c but it give an error message as follows ./encoder_example -v 1 file_1.yuv > file_1.ogg Input file file_1.yuv is neither a WAV nor YUV4MPEG2 file. so the error message is understandable for anyone. when this file is play with mplayer it shows as follow

Hello, I wrote a theora video encoder based on etheora (and the examples provided with it) for Processing IDE (processing.org). I have some problem with the quality of encoded frames. eg. http://poux.be/tmp/movie.ogg And when I play the movie with mplayer or totem, the video resolution is changed from 640x480 to 854x480 (when i use ETHEORA_ASPECT_NORMAL in etheora_enc_setup). And if I try to

Does anyone have any R code or suggestions on how to generate a population that follows a Neyman-Scott process? More specifically, I'd like to randomly generate both the parents and the children from Poisson distributions and the children locations from a bivariate normal onto an N by N grid. If the locations spill over outside the grid, then I'd like to reflect those locations back into

Dear R-users, I am exploring disease spread in trees. I have locations for diseased trees in 2004 and 2005 and want to know whether the patterns are independent. I would like to use both the 'gcross' and 'kcross' functions (in spatstat). I imported the data from two text files and created point objects using as.ppp. I then created a marked planar point pattern using ppp. I am
