lapply - value changes as parameters to function?
Hi,
I'm trying to get better at things like lapply but it still stumps
me. I have a function I've written, tested and debugged using
individual calls to the function, ala:
ResultList5 = DoAvgCalcs(IndexData, Lookback=5,
SampleSize=TestSamples , Iterations=TestIterations )
ResultList8 = DoAvgCalcs(IndexData, Lookback=8,
SampleSize=TestSamples , Iterations=TestIterations )
ResultList13 = DoAvgCalcs(IndexData, Lookback=13,
SampleSize=TestSamples , Iterations=TestIterations )
ResultList21 = DoAvgCalcs(IndexData, Lookback=21,
SampleSize=T...

predict.glm -> which class does it predict?
...e logistic regression model in R
model <- glm(T ~ ., data=d.f(Y), family=binomial) (Y is the dataset of
the Proteins).
This works fine. T is a factored vector with levels cancer, noncancer.
Proteins are numeric.
Now, I want to use predict.glm to predict a new data.
predict(model, newdata=testsamples, type="response") (testsamples is
a small set of new samples).
The result is a vector of the probabilites for each sample in
testsamples. But probabilty WHAT for? To belong to the first level in T?
To belong to second level in T?
Is this fallowing expression
factor(predict(model...

I did a bit more testing, and ended up creating a set of testsamples, as
follows:
ideal.pcm => me saying "This is what I'd like to hear"
junk.pcm => me saying "With a bit of luck, this is gone"
mixdown.pcm => ideal.pcm, with junk.pcm started 7 ms later and 3 dB lower.
(All of this as 8000 Hz, 16-bit signed)
I then copied junk.p...

The problem with that is that it'...

trouble getting speex_echo_cancel() to work
I'm trying to convert my current headphones and microphone chat
application to support loudspeakers and microphone, and so I thought I'd
give speex_echo_cancel() a try.
Since my users quite frequently have other sound-producing applications
running on their computer (such as winamp), I sample 'wave' recording
device of the soundcard in addition to the microphone.
I then call
