Hello R users, I am looking for R (or S) code related to group sequential or adaptive designs for clinical trials. (The most prominent examples are the designs of Pocock or O'Brien/Fleming, the alpha-spending function approach, or Fisher's combination test and the inverse normal method.) I am particularly interested in the calculation of the critical boundaries, the handling of spending

Dear R users, can someone help with these short puzzles? 1) Is there a function like outer() that evaluates a three-argument function on a threedimensional grid - or else how to define such a function, say, outer.3()? E.g., calculate (x/y)^z on (x,y,z) element of {1,2,3}x{3,4}x{4,5} and return the results in a 3-dimensional array. I would naively use outer() on two of the arguments within a

Dear R-users, thanks for your help last time! But now I've got a new problem with my simulation program. In order to save time I decided to divide my program in different parts. So I can use several computers (at the moment 3). On all these computers I installed the R-version 1.7.1. One works without problems. The other 2 don't work. During program`s running Rgui.exe causes an error,

I'd like to program a simulation of recurrent events to test few models in R. Is there anybody who has experience of that and could give me advice? Your help is greatly appreciated!

Hallo to everybody out there, I have downloaded and compiled Samba3b2 on a SuSE 8.2 machine. For testing purpose, I connect to this machine with a Win2k-Box ... most things seem to work fine, but I am unable so change passwords from the win-box with unix password sync enanbled. I changed loglevel to 103 and enabled password chat debug. From what I found in the log-files, I can conclude that

Hi Marc, I encountered the problems even with older versions of speex, including 1.2beta2 and 1.1.12, too. I had no time in the last weeks to investigate this issue further, sorry. Hopefully, I'm able to do some more test the next days, but I have no real idea how to proceed Performance and quality seem to be o.k. for me if I deactivate the Blackfin optimizations inside the file

Hi Jean-Marc, I did some further checks with 1.2 beta 3: The problematic function is DIV32_16 inside fixed_bfin.h. When I comment it out (i.e. replace it by the generic version of the routine), the quality improves significantly. Nevertheless, there is still a horrible distortion when there is some overdrive/saturation in the input signal. For me, it looks like there's an instable filter

Hallo Liste Derzeit mache ich meine ersten Gehversuche mit Linux (SuSE). Bis jetzt habe ich in einem kleinen Netzwerk f?r meine Tauchschule vier Rechner betreut. Einer davon war WinNT-4.0 Server und Arbeitsplatz zugleich. Nachdem ich nicht mehr bereit bin, mich mit dem w?chentlichen "blue screen" und dem monatlichen Neuinstallieren von NT abzufinden, bin ich derzeit beim Umsteigen auf

Hi Jean-Marc, didn't get a reply to my last post (see below) -- do you have no idea what happens here? After some more tests, I disabled the DIV32_16 Blackfin optimizations and now get good quality on the Blackfin. But when I have overdrive on the input, things become very bad -- I'm not sure if this is really a filter stability issue like I wrote some weeks ago. I use the speex

Hi all, i am trying to run Samba 2.2.3a under a RedHat 7.2 i386 machine. After i compiled and installed the packages, i made a smb.conf up. Just some standard stuff nothing special. Now, when i start smbd and then check it with smbstatus it gives me this error : Samba version 2.2.3a Service uid gid pid machine ---------------------------------------------- tdb((null)):

Hello to all, after noone bother my subject. I think I'm all alone making mistakes on this thing. But I should really know if it is possible to mange the administration of samba in an comfortable way. After all the years I worked with it I never did manage it to be in an sufficent manner. Is there a plan in the future to have a central administration within the samba package? --------

Hello everybody, I'm currently trying to run speex on the Blackfin (BF-537) STAMP evaluation board unter uCLinux. Using 1.2 beta 3, I encountered problems when activating the Blackfin assembler optimizations. Without optimizations for blackfin, i.e. calling ./configure --enable-fixed-point --host=bfin-uclinux everything seems to work fine. But when I add the --enable-blackfin-asm flag to

Hi, when I compile with FIXED_DEBUG enabled, I get an error -- both when make tries to build testenc.o and when I try to link my app against the speex lib: lorenz@panelmaker:~/Blackfin/tests/speex_loopthrough$ make bfin-uclinux-gcc -c -g -I/home/lorenz/include -o main.o main.c bfin-uclinux-gcc -gl -elf2flt -L/home/lorenz/lib -o speex_through main.o -lspeex_debug -lspeexdsp -lm

Hello. =) I''m having a bit of trouble with my nfs xen installation and have spent much time trying to research/figure out this problem with no luck, so I''m hoping someone might be able to help me here. =) I''ve successfully installed xen 3.02 on Linux RH4 on my Sun single proc opteron v20z server. I''ve installed what I believe to be a base Linux OS on a

Hello, The example shows a sequence of songtypes a bird has sang. The entire list contains several thousand songs which the bird has produced consecutively. Is there any convenient way in R to produce a contingency table which shows how often a special song type was sang after a special other songtype? Or within a determined frame of e.g. 10 consecutively produced songs? Example: Nr Songtype 1

Hello R-Members, can anyone explain the difference between multiple and multivariate regression to me in terms of the terminology and eventually its respect to the mathematical foundation respectively ? Is multiple regression perhaps more related to GLM and multivariate Regression rather applied, if there are no explizit numeric factor levels ? Thanks for elucidations on that topic. Many

Asterisk 11.1.0 One queue with strategy=leastrecent. (Full queues.conf below.) Occasionally (several times today), a caller will get "stuck" in the queue - there are operators available to take the call, but the caller stays in the queue for a long time. Any idea what might cause this, or where I can start looking to debug it? I'm going to start digging through the queue log
