My first question - has anybody installed Rsprng on OS X? The link

Dear Rolf,
One thing that sometimes makes nls easier to apply is using the 'formula'
argument like you would use the 'fn' argument of optim. That is, if you
have a residual function that has arguments x, y, a, b and you need to
optimize a and b, you would make a call like

That's the problem. You need to build a shared library version, not a

Dear Experts, this is more a general stat question, I tried to ask in other
places but had no luck with answers (expect one that suggested numerical
instead of analytical optimization):
The likelihood below is a mixture of two negative binomial
distributions:
P*f(n;x1,x2,E) + (1-P)*f(n;x3,x4,E)

As far as i know mixture modelling (sums of exponentials) cant be done
in SAS or SPSS. For R there is the Rmix package that while not very
user friendly at least works.

Your example works for me.
Please read the posting guide that asks you to provide the following
important information for us:
Which version of R is this?
Which version of the package?
The recent version on CRAN master is:
Package: clim.pact
Version: 2.2-13
Date: January 10
Dear All,
I would like to make the derivation of a points.
I tried to use D1tr (linear interpolation).
I also tried to used D1ss (spline interpolation) but I do not realy know
how to choose the smothing parameter the best.
D1ss(x, y, xout = x, spar.offset = 0.1384, spl.spar=NULL)
Here is an exam

Dear all,
It appears that the function is.factor() returns different results when
used inside the apply() function: that is, is.factor() fails to
recognize a factor..
Where is the trick?
many thanks,

I think you need:
dx2 <- exp(dx)
dp2 <- dp / dx2
sum(c(0, diff(dx2)) * dp2)
I hope it helps.

Hello!
I want to do a non-linear regression with 2 explanatory variables
(something like : length ~ a * time * exp( b* temperature)), having a
data set (length, time, temperature). Which function could I use (I
tried nls but I think it doesn't work)
Thanks a lot!

No hit key solution sorry, but may help :
if (file.exists('zefile')) stop()
allows to stop given zefile is created

Hi
I have a dataset of absolute growth rates g ranging from close to 0 to
around whatever of which I want to calculate a pdf.
If I use density(g) the pdf will extend to below 0 so I logtransform g
and do d <- density(log(g)).
Now I would like to transform this pdf back, i.e. d$x <-
exp(d$x) but wh

Like the Law of Fives, it depends very much on the ingenuity of the
user; how's that for a fast answer?
