pulling out 1 country and 1 wave
Hello.
I am trying to pull out one country from a time series of 5 waves. For example I need Norway from the 5th wave. This is new to me. Typically, I work with country specific surveys.
data = norway
I have attached a .tiff of the codebook showing the variable names for Norway and the wave. They appear to be Norway = v218 and wave = v15. But perhaps I am wrong and this is part of the

wave/OSS and JumpStart Kindergarten...
Warning: WINE Newbie Alert. Proceed with caution....
Background: I don't want to fork up $$$ for a separate Windows machine for my
kid so I've decided to see if I can run any of the popular brain-rot software
under WINE (Is it "WINE" or "Wine" or "wine"?) on a Linux 2.4.18 kernel. My
first project is a vintage 1995 version of JumpStart Kindergarten.

First ever Open Source Asterisk / Wave bounty
I've just received an email from a colleague who told me to put my
money where my mouth is ....
So here it is - I'm offering $500 and looking for other people to add to
this bounty.
We can get a group of people putting matching funds up to finalize the
scope of the first Open Source Asterisk / Wave conference call
integration robot bounty but if you have any other suggestions feel free

Mono wavs with b4
When I encode a monophonic wav file, I would expect the resulting ogg file
to be at about half the bit rate specified on the command line, as stated in
the "oggenc -h" help text: "The 6 modes are approximately 112, 128, 160,
192, 256, and 350 kbps (for stereo 44.1kHz input. Halve these numbers for
mono input).".
This doesn't seem to be happening, though. I took a 16-bit,

Best way to export values from a function?
Maybe there is a great website out there or white paper that discusses this but again my Google skills (or lack there of) let me down.
I would like to know the best way to export several doubles from a function, where the doubles are not an array.
Here is a contrived function similar to my needs:
multipleoutput<-function(x)
{
squared<-x^2
cubed<-x^3
exponentioal<-exp(x)

Fitting a sine wave using solver
Greetings,
I have several sets of oscillation data and would like to estimate the
parameters of a sine function to each set (and hopefully automate
this). A colleague provided an excel sheet that uses solver to minimize
the RSS after fitting the sine function to each data set, but this
cumbersome and difficult to automate. Is there a method in R for
fitting a given sine function to a

fitting periodic 'sine wave' model
I have been attempting to estimate the periodic contribution of an
effect to some data but have not been able to fit a sine wave within R.
It would be nice to start by being able to fit a sine wave with an
amplitude and frequency.
x<-seq(0,20,by=0.5)
y<-2*sin(2*pi*.5*x) #amplitude =2, frequency=0.5
# This failed to converge
r<-nls(y ~ A*sin(2*pi*F*x), start=list(A = 1, F = 1),

create waveform sawtooth
My tuneR sawtooth wave function generator is broken.
When I use the sine function, I get exactly what I expect: a sine wave whose frequency is defined by the freq parameter. In particular, higher frequencies have shorter wavelengths (more cycles per second means shorter waves). When I create a sawtooth wave, the opposite seems to occur: higher frequencies result in longer waves. But that?s not

fitting sine wave
Dear R-helpers
?
I have 7 data points that I want to fit a continuous curve to, that should look similar to a sine wave
My data points would mark the local minima and maxima respectively.
This is what I?ve got so far. And I would keep doing so, but sadly nls() then says that it has reached the maximum number of Iterations?

Determining frequency and period of a wave
Hello! I'm collecting data on a refrigerator that I'm using to cure
meat. Specifically I am collection humidity and temperature readings.
The temperature readings look sinusoidal (due to the refrigerator
turning on and off).
I'd like to calculate the frequency and period of the wave so that I can
determine if modifications I make to the equipment are increasing or
decreasing

OPUS encoding mono sine wave
I wonder if anybody try to compress a pure sine wave using OPUS codec.
When I compressed the mono 1KHz, 16bits 48000 samples per sec. audio stream using the 'opus_demo' utility:
opus_demo -e audio 48000 1 2min_1kHz_Sine_16bit_48kHz.wave 2min_1kHz_Sine_16bit_48kHz.opus_raw
I had the output stream that is shown below.

create waveform sawtooth
Ccing the maintainer if the tuneR package.
Looks to me like sawtooth (and square) don't behave as expected when using xunit="samples". Workaround is to use xunit="time" instead:
sawtooth(110,duration=1/100,samp.rate=sample_rate,xunit="time")
I looked at the code but found it to be opaque.

mdf -- better adaption of W?
Hi,
I'm still working on visualizing the echo canceller, but I discovered
something that might be interresting.
During testing, i did this:
Generate a test signal (10+x sine waves per frame), where x increases by
one for each iteration, and wraps around at 100.
Set the speaker signal for the frame to the test signal.
Add 0.5*test signal to the mic signal.

[PATCH] Improve LPC order guess
Hi,
This patch improves compression a very tiny bit on average, but
up to 0.1 percentage point for classical music. I haven't found
any tracks that show worsening compression with this patch.

Beta3 impressions
I tested Vorbis encoder - beta3 version, and here are my thoughts:
- In comparison to beta2, subtle high-frequency artifacts seem to be gone
(though they were small in beta2). Good job there! :-)
- Velvet.wav also sounds better, but transparent quality is reached
at -b256+.
- Horn.wav still sounds very sucky, mode -b256 gives ~100kbps (this
is understandable because in this sample practically
