mysql frontend for linux.
Hi list.
I''m using Ubuntu distro. for rails development. Today, to my disappoint,
I''ve found that there''re certainly almost no mysql frontend which runs
very well.
(1) mysql-query-browser: Seems to be very nice. But, it quickly exits
when I press ctrl+enter or modify a table structure. Something strange
is happening here, but I can not figure out what it is.

nls question
I'm running into problems trying to use the nls function to fit the some
data. I'm invoking nls using
nls(s~k/(a+r)^b, start=list(k=1, a=13, b=0.59))
but I get errors indicating that the step has been reduced below the
minimum step size or an inifinity is generated in numericDeriv. I've
tried to use a variety of starting values for a, b, k but get similar
errors.
Is there

Sure thing. It prints "0". Calling that inifinity is somewhat
of a stretch, isn't it ?

Yes, that's exactly what I meant... thanks for reading my mind! :)

OK, details:
I run RH8 (gcc 3.2.something), RH9 (gcc 3.2.2-5) and Fedora.
Problems are the same across all setups. Hardware is Athlon 1600+
and half a giga RAM. Runs fail with an assertion when the linear
scan allocator is enabled, but runs without problems otherwise.
On RH9 (the system I have access to while generating this email) I

2 questions, frame size and SPEEX_GET_LOOKAHEAD
Hi, Andras,
Thanks for the comments. Yes, I am aware of those issues. I probably
should have been more accurate on my usage of terms. Actually in my
project, the unit collection is a mixture of diphones and words.
However seems to me, these synthesizer specific issue is irrelevant to
my question about speex. As you said, i merely use speex as storage
methods. All I ask for is to get the

2 questions, frame size and SPEEX_GET_LOOKAHEAD
Ok, let me first explain why 5ms matters, even they are 0's, in my
particular application.
I am working on a speech synthesis system. The basic idea is
concatenating pre-recorded phonemes or words into longer sentences. So
any missing or extra samples, even it is as short as 5~10ms, cause
very noticeable discontinuities.
I want to use speex to compress/decompress those pre-recorded

2 questions, frame size and SPEEX_GET_LOOKAHEAD
[At the risk of educating you about something you might already know]
Natural speech in most human languages gradually changes from one
phoneme to the next.
Concatenating phonemes together from a fixed, prerecorded, unflexible
set would give rise to abrupt changes between them (both in phoneme
quality and in pitch), and thus make the resulting speech hard to
understand and/or uncomfortable

Infinity Combat Prototype OpenAL problems
According to the AppDB, the Infinity Combat Prototype works perfectly. Unfortunately, when I try to run it, it freezes when it tries to load OpenAL. I've tried installing the OpenAL stuff linked to on the DB entry: no effect. Stderr shows nothing useful when running it and running it with WINEDEBUG=+openal32 shows nothing more.

nls: Missing value or an Infinity produced when evaluating the model
Hi,
I am trying to fit a sigmoid curve to some data with nls but I am getting
into some trouble.
Seems that the optimization method is getting down to some parameter
estimates that make the equation unsolvable. This is an example:
>growth<-data.frame(Time=c(5,7,9,11,13,15,17,19,21,23,25,27),BodyMass=c(45,85,125,210,300,485,570,700,830,940,1030,1120))

The gamma function and infinity
I have to calculate some formula like:
gamma(x)/(gamma(x+y)
and I observed that for relatively big values of x, R
returns infinity and so cannot compute the formula. Is
it possible to force R to give the real value of
gamma(x) instead of Inf ?
thanks

sum to infinity
Hi r-users,
How do we evaluate the summation of (1/m!) from 0 to infinity (for example).
Any help is very much appreciated.
Thank you.

Nonlinear regression / Curve fitting with L-infinity norm
Hello everyone,
I am looking into time series data compression at the moment.
The idea is to fit a curve on a time series of n points so that the maximum deviation on any of the points is not greater than a given
threshold. In other words, none of the values that the curve takes at the points where the time series is defined, should be "further away" than a certain threshold from the

infinity in integrate function in R
sorry the integration was from -Inf to 1.96
The integrate function in R is not taking Inf (infinity). How do you use
infinity in R. I was doing: integrate(dnorm,- Inf, 1.96) and I was getting
Error: NA/NaN/Inf in foreign function call (arg 2). Obviously this should
be equal to pnorm(1.96)= 0.9750021. How do you get around the infinity
problem in R?

Bug Report: read.table with UTF-8 encoded file imports infinity symbol as Integer 8
There seems to be something odd with "?" on Windows (and not only with
read.table)
In native encoding (cp-1252 in my case), "?" gets converted to "8"
x <- "?"
Encoding(x)
#> [1] "unknown"
print(x)
#> [1] "8"
charToRaw(x)

"?" is indeed "8"
identical(x, "8")

Symbolic substitution in parallel; use infinity symbol?
I'd like to be able to modify axlab in (C) below so that 'Inf'
is replaced by the infinity symbol.
y <- rnorm(40)
breaks <- c(-Inf, -1, 1, Inf)
x <- cut(y, breaks=breaks)
plot(unclass(x), y, xaxt="n", xlab="")
## A: The following gives the axis labels "(-Inf, 1]", etc.
axis(1, at=1:3, labels=expression("(-Inf,-1]", "(-1,1]",

nls: "missing value or an infinity" (Error in numericDeriv) and "singular gradient matrix"Error in nlsModel
Hi,
I am a non-expert user of R. I am essaying the fit of two different functions to my data, but I receive two different error messages. I suppose I have two different problems here... But, of which nature? In the first instance I did try with some different starting values for the parameters, but without success.
If anyone could suggest a sensible way to proceed to solve these I would be

Float::INFINITY ranges in where() clause
This seems like such an obvious idea that I''m having trouble believing
I''m the first to think of it. Why not take ranges containing
Float::INFINITY and translate them to the appropriate greater than or
less than comparisons? Example:
class Person
scope :voters, -> { where(born_on: (-Float::INFINITY..18.years.ago)) }
end
This would generate something along the lines of

Tomas,

principle, we could change this particular conversion in RGui to avoid the
substitution.
Not sure whether I am missing something here, but I used RStudio for my
examples (I should have said) and David's mentioned RStudio as well, so it
