Josh, Yes, you can change VBR quality or ABR average bitrate at any time. You don't need to do anything special. I use this feature (changing VBR quality midstream) from time to time and it's quite convenient.

Some other folks more closely tied with Xiph probably can comment more on that issue. -- Keith Kyzivat SIPez LLC. SIP VoIP, IM

This release introduces a couple of new options for existing extensions: * A new option PresentOptionAsyncMayTear for the Present extension, * A new flag XFixesClientDisconnectFlagForceTerminate to the XFixes XFixesClientDisconnectFlags intended to be used by screen lockers, where the server must exit if the screen locker does. The other changes include various fixes, clarifications

Fantastic! Thanks Tom. (if only it was possible to change the VBR target on the fly for the H264 codec we've licensed :-) ) Cheers, Josh On Apr 11, 2008, at 2:39 PM, Tom Grandgent wrote: > Josh, > > Yes, you can change VBR quality or ABR average bitrate at any time. > You don't need to do anything special.

Hello: I would like to be able to do a 3D scatter plot from 3 variables, 2 independent and 1 dependent. The closest R function I could find for this is "cloud". However cloud uses, as input, a matrix where the value of each matrix element is the dependent variable value at that matrix coordinate. My problem is that the independent variable values are floating point and can be of

Hi Folks! Just started using the gamlss package and I tried a simple code example (see below). Why the negative sigma?

Hi, I have a problem with a regression I try to run. I did an estimation of the market model with daily data. You can see to output below: /> summary(regression_resn) Time series regression with "ts" data: Start = -150, End = -26 Call: dynlm(formula = ror_resn ~ ror_spi_resn) Residuals: Min 1Q Median 3Q Max -0.0255690 -0.0030378 0.0002787

Hi, I am analyzing a data set with greater than 1000 independent cases (collected in an unrestricted manner), where each case has 3 variables associated with it: one, a factor variable with 0/1 levels (called XX), another factor variable with 8 levels (X) and a third response variable with two levels (Y: 0/1). I am trying to see if X1 has an effect on the relationship between X2 and the

The following cut command takes nearly 10 seconds on my machine even though the length of input vector is only 6. I am running on Windows Vista with C2D BLAS using R 2.11.1. Using the default BLAS and either R 2.10.1 or "R version 2.12.0 Under development (unstable) (2010-05-31 r52164)" also gives me results in the 9-11 second range. I would have expected it to take much less time.

Hi Folks, If you need to send data from Java to R you may consider using the JDataFrame API -- which is used to convert data into JSON which then can be converted into a data frame in R. Here's the project page: https://coherentlogic.com/middleware-development/jdataframe/ and here's a partial example which demonstrates what the API looks like: String result = new JDataFrameBuilder()

Hi Simon, Thanks for your feedback. -- this is an observation that I wasn't considering when I wrote this mainly because I am, in fact, working with rather small data sets. BTW: There is code there, it's under the bitbucket link -- here's the direct link if you'd still like to look at it: https://bitbucket.org/CoherentLogic/jdataframe Re "for practical purposes is

Hi, Here is the summary-output of the Coxph-model I used (the output is based on the best final model i.e. all significant explanatory variables and their interactions are included): coxph(formula = Y ~ LT + Food + Temp2 + LT:Food + LT:Temp2 + Food:Temp2 + LT:Food:Temp2) n= 555 coef exp(coef) se(coef) z

I am trying to replicate the results of an aov command with lmer, to understand the syntax, but I can't quite figure it out. I have a dataset from Montgomery p. 520 with a nested and factorial layout. There are 3 fixtures, 2 layouts (the treatments) in a factorial design, but the operators who perform the runs are nest in layouts (4 operators per layout=8 different operators). Thus, each

I found out the other day that crossprod() will take a single matrix argument; crossprod(x) notionally returns crossprod(x,x). The two forms do not return identical matrices: x <- matrix(rnorm(3000000),ncol=3) M1 <- crossprod(x) M2 <- crossprod(x,x) R> max(abs(M1-M2)) [1] 1.932494e-08 But what really surprised me is that crossprod(x) is slower than crossprod(x,x): R>

A number of as.data.frame methods do names(x) <- NULL Replacing that with if(!is.null(names(x))) names(x) <- NULL appears to save making one copy of the data (based on tracemem and Rprofmem in a copy of R compiled with --enable-memory-profiling) and gives a modest but consistent boost in speed, e.g.: # old new # user system

Tom, this may be good for embedding small data sets, but for practical purposes is doesn't seem like the most efficient solution. Since you didn't provide any code, I built a test case using the build-in Java JSON API to build a medium-sized dataset (1e6 rows) and read it in just to get a ballpark (see https://gist.github.com/s-u/4efb284e3c15c6a2db16 # generate: time java -cp

Hi, I have a fairly simple linear regression using the lm function. There are about 100 variables and 30,000 rows of data. It runs fine and produces a decent looking R2 value. I'm interested in performing a stepwise variable selection to see if things can be cleaned up a bit. Calling the step function returns ONE iteration (all the variables) and then stops. No errors are reported.
