How to do a trig regression
Hello All,
I cant seem to do a trig regression in R.
The equation is as follows : y = a+b*(sin((2*pi*x/360) - c))^2
a, b, c are coefs that I want.
y, x are input vectors.
The equation I put into R: lm(y ~ sin(2*pi*x/360)^2)
This equation is missing the c and I dont get the right answer.
Also, I dont know how to plot the lm over the x values instead of the
indices.
Any help is sincerely

Historical Libor Rates
Hello All,
Does anyone know how to download historical LIBOR rates of different
currencies into R?
Or if anyone knows of a website that holds all this data...I only need up to
january of 2000.
Also, how can we make the row names the index of a plot (the names of the x
values)?

Help with time in R
Hi,
I have a problem with the time formatting in R. I have entered time in the format "MM:SS.xyz" and R has automatically classified this as a factor, but I need it numerically. However when I use as.numeric() it gives me totally different numbers. Is there any way I can tell R to read thes input as a number?
Thank you very much

Where to find the p-value of a correlation test
Hey everyone,
I hope this finds you in good cheer.
I just have a quick question: What is the function that outputs the p-value
for correlation?
cor(x,y) only provides the R value. I would like the p-value associated
with it.
Thank you all for your help!

problem with location of libraries 64-bit (opensuse)
Dear list,
there seems to be a problem with the standard location of R?s 64-bit libs
at least under openSUSE.
I had two user questions regarding the compilation of rpy2 for 64-bit systems.
Personally I don`t know rpy2 but maybe someone on this list can decide if
the mistake lies on R`s side or on rpy2?s side or in between.
R-devel is installed in these cases, I asked. Latest R-base or

Installing rpy2 on Red Hat 6

Possible bug: How does libR.so find RHOME?
Hi
While installing RPy2, I had curious problems which, if I traced them
back correctly, have their root in the way that libR.so find the R
installation directory. I wonder if this might be a subtle bug that only
causes problems when one has several versions of R on one system but
then can be very annoying and cause very strange behaviour.
It seems to me that libR.so asks the Unix shell to

windows directory structure
Hi,
I have some trouble to get the Python bindings RPy2 running with
the latest release of R. I'm using Windows.
The reason is, that RPy2 looks at certain places for R.dll,
as $R_HOME/bin and $R_HOME/lib, but not at $R_HOME/bin/i386
where the dll is located on my machine.
So I suspect that the directory structure has changed and the
RPy2 team did not notice it. I would like to discuss a

Issue when calling deparse(substitute(x)) from C with "anonymous" R vectors ?
Dear list,
When calling R from C, what appears like a spurious error can be
triggered during the execution of chisq.test(x, y).
This is happening when the following conditions are met:
- x and y are "anonymous" C-level R vectors (they do not have a symbol),
but they are protected from garbage collection
- x and y are "not too small" (it was experienced as soon as they are

C-API: check whether R has been initialized ?
Beside the possible argumentation that with an API elegance and convenience
might sometimes be superior to necessity, the suggested pattern ("every
program, including R itself, keeping its own flag") does no work too well
when the nested embedding of R is involved.
A concrete example is:
```
$ R -q
> library('rPython'); python.exec('import rpy2.robjects')

How to change Rlapack by lapack (for rpy2 installation)?
(I asked an earlier question on the rpy2 installation
to the rpy2 list, the solution there was to
edit the setup.py script, but this looks beyond what I can do unless
someone tells me exactly what to modify).
I have R 2.8.1 on 2 machines running ubuntu 8.04
(packages R-base and R-base-dev, among others, installed using Synaptic)
and while the installation
of rpy2 went fine on machine1, failed on

Definition of uintptr_t in Rinterface.h

I was recently pointed out that a definition in Rinterface.h can be conflicting
with a definition in stdint.h:

/usr/include/stdint.h has:
typedef unsigned int uintptr_t;

C-API: check whether R has been initialized ?
rPython appears to provide an interface from R to Python by embedding
Python and I'd think that it can safely assume that R has been initialized,
but might not be the point here.
The issue is that a Python package embedding itself R (here rpy2) appears
to have no way to know that earlier in the life of the process R was
initialized.
