Dear R-list members, I need an help with the Multidimensional Scaling analysis (MDS). So far I used the cmdscale() command in R, but I did not get the perceptual map I would love to see, and I would like to know if it is possible to get it using R, and if yes how. I also had a look to the functions isoMDS() and sammoc() but with no luck. I summarize the experiment I performed, and I would ask you

Hi R-help members, I have read a lot in the Archive about the "Type I" vs "Type III" sum of square. I think I have read confusing post so I want to have a clear idea of the problem. Here is an example. I have 3 groups of subjects of unequal sample size (G1 (n=7), G2 (n=7), G3 (n=4)). for Each subject I have 4 measures corresponding to the crossing of 2 factor (A & B)

Hi everyone, I'm a newbie to R and to linear mixed effects modeling, so please have mercy :-) Just wanted to check, whether what I'm doing is alright. I've collected data concerning tonotopic organization of the auditory cortex in humans, and I have approximately 1400-1800 data/time points per person (13 in total). Observations were made how the focus of neuronal activity changed

Golly, anyone who read Plato's Dialogues would realize that the Socratic method involves patiently leading the questioner stepwise through the solution, not simply writing RTFMeno. Jim

Would it be possible to set the ringtone based on the number that was dialed? Example of what the goal is: Dial Denver number Incoming calls ring with ringtone 1 Dial main number Incoming calls ring with ringtone 2 We are currently using Digium D40, D50, D70 phones. -------------- next part -------------- An HTML attachment was scrubbed...

Hi R-ers, I'm wondering if anyone has investigated a method for embedding audio files in R graphs (pdf format), and allowing their playback to be triggered interactively (by clicking on a graph element for instance). I know how to do this in latex pdfs with the multimedia package, but it seems that R would provide a more appropriate platform for many reasons. Thanks for any help you

I'm using Opus for a networked ham radio communications receiver. Kudos on the whole project; it sounds excellent even at low bit rates and the API was surprisingly simple and easy to use. And god knows the world needs a really good, general purpose, non-proprietary codec. One question, though. Depending on the mode my receiver can generate mono or stereo. Most operating modes are mono, but a

Since 2008, Microsoft (formerly Revolution Analytics) staff and guests have written about R every weekday at the Revolutions blog (http://blog.revolutionanalytics.com) and every month I post a summary of articles from the previous month of particular interest to readers of r-help. In case you missed them, here are some articles related to R from the month of August: Using the featurizeText

Could someone point me to the BARK/MEL tables that these macros (from vorbis/scales.h) are trying to approximate? #define toBARK(f) (13.1*atan(.00074*(f))+2.24*atan((f)*(f)*1.85e-8)+1e-4*(f)) #define fromBARK(z) (102.*(z)-2.*pow(z,2.)+.4*pow(z,3)+pow(1.46,z)-1.) #define toMEL(f) (log(1.+(f)*.001)*1442.695) #define fromMEL(m) (1000.*exp((m)/1442.695)-1000.) I was wondering if I could come

Hello, thanks for bringing this topic up, and it would be excellent if we could come of with a generic solution for this in base R. It is one of the top frequently asked questions and requested features in parallel processing, but also in sequential processing. We have also seen lots of variants on how to attack the problem of reporting on progress when running in parallel. As the author

Dear R-help members, I'm trying to run LME model on some behavioral data and need confirmations about what I'm doing... Here's the story... I have some behavioral reaction time (RT) data (participants have to detect dome kind of auditory stimuli). the dependant variable is RT measured in milliseconds. 61 participants were tested separated in 4 age groups (unblanced groups,

Hello R-devel, A function to be run inside lapply() or one of its friends is trivial to augment with side effects to show a progress bar. When the code is intended to be run on a 'parallel' cluster, it generally cannot rely on its own side effects to report progress. I've found three approaches to progress bars for parallel processes on CRAN: - Importing 'snow' (not

>Yesterday I have finished writing the ambisonic pan filter for oggenc. May I ask what this "pan filter" is? I made some tentative suggestions for coupling Ambisonic B-format in a post "Vorbis Ambisonic coupling" on 4feb07 I gather from the last monthly meeting, that some of you, including Monty, had problems with the phase behaviour of B-format. Would anyone like a

??Hi all! We use Samba 3 server for some video stuff (editing, rendering, and so on) -- that's why performance is critical. We've tried a lot smb.conf options, but Samba can't satisfy our requirements. Our server configuration is as following: * Hard drive: RAID5 (8 x Seagate 7200.10), 3ware 9550SX-8LP controller * NICs (trunked): 2 x Broadcom NetXtreme BCM5704 * Processor: Opteron
