Bessel function
Dear all
Currently, I'm implementing the generalized hyperbolic distribution into
Splus. Unfortunately the Bessel function is not implemented in Splus. In
R the Bessel function does exist but it is an internal function and I'm
not able to look at the code.
Is there any possibility to see the code of the Bessel function in R or
does anybody has an implementation of the Bessel function in

Modified Bessel Function - 2nd kind
In order to fit a probability distribution proposed by Sichel [Journal of
the Royal Statistical Society. Series A (General), Vol. 137,
No. 1. (1974), pp. 25-34], I need a modified Bessel function of the 2nd
kind. I notice that the base package of "R" only has modified Bessel
functions of the 1st and 3rd kind. Does a modified Bessel function of the
2nd kind exist anywhere?

format text help pages Windows
Dear list,
Could someone enlighten me a bit on the
exact format used for text help pages
as I see them on Windows in the help/

When opening an example of these files
in a text editor (?Bessel in GNU emacs),
the file is displayed as follows:

computing roots of bessel function
I am not yet a R user but I will be soon.
I am looking for the R command and syntax to compute the roots of Bessel
function i.e. computing the z values that lead to Jnu(z)=0 where J is a
Bessel function or order nu.
May You help me ?
thanks in advance.

Bessel function with large index value
I am looking for a method of dealing with the modified Bessel function
K_\nu(x) for large \nu.
The besselK function implementation of this allows for dealing with
large values of x by allowing for exponential scaling, but there is no
facility for dealing with large \nu.
What would work for me would be an lbesselK function in the manner of
lgamma which returned the log of K_\nu(x) for large

underflow handling in besselK (PR#2179)
The besselK() function knows about overflows/underflows internally;
there is a constant xmax_BESS_K in src/nmath/bessel.h (and referred to
only in bessel_k.c), equal to 705.342, which is checked if expon.scaled is
FALSE. (The equivalent number for bessel_i.c is 709, defined as
exparg_BESS in bessel.h.) However, besselK(x) silently returns +Inf if
x>705.342. This behavior is reasonable for

Maple and R
Hi R-users,
Can Maple function be exported to R?
I have a jacobian matrix (4X4)?from maple in algebraic form which involve modified Bessel function of the first kind.
I just wonder whether we can use algebraic form into R before the value of the parameters can be estimated.
Thank you so much for your attention and help.

Existence of non-vectorised functions
Dear R-Group:
Recently, I ran into a problem. I was using a function called "I.1",
which evaluates the first-order modified Bessel function of the first
kind, in the package "CircStats". This function is not vectorized,
since it uses a couple of "if" conditions. However, when I called this
function with a vector argument, I got no error/warning messages in

[Rd] Re Bessel functions of complex argument
Dear all,
I'm writing a code that requires Bessel functions with complex argument.
Searching the list, I found the continuation of a thread I initiated a few
months ago:

As I understand, the most promising option would be to use the fortran or C

Documentation for sd (stats) + suggestion
I cannot file suggestions on bugzilla, so writing here.
As far as I can tell, the manual help page for ``sd``
?sd
does not explicitly mention that the formula for the standard deviation is
the so-called "Bessel-corrected" formula (divide by n-1 rather than n).
I suggest it should be stated near the top.
I would also suggest (feature request!) that either

R 1.3.1 fails 'make check' on arm in the Bessel example (PR#1097)
Debian tries to build its packages on a variety of platforms. The arm
platform compiled 0.90.1 (the last Debian release before the Debian package
required an Atlas library, something we no longer require) failed in 'make
check'. The log snippet follows; I traced this to the example(Bessel) code.

Modified Bessel function (third kind)
Hi:
There is a Modified Bessel function (third kind,
real order) besselK in R. Is there a C version of this
function?
I can only find a Fortran function rkbesel on
http://www.netlib.org/specfun/. However, this rkbesel
fortran function is the second kind.
Thank you!

gcc 3.2.1
gcc 3.2.1 is out and avoids the warnings about -I/usr/local/include

Unfortunately, it seems to generate invalid code on 32-bit Solaris 2.7.
(64-bit code via -m64 is OK.) On two separate installations
example(Bessel) crashes in graphics.c because dd is not being passed down
from clipText correctly. I don't think that is all, as compiling

Extending deriv3()
Hello,
I was wondering if the functions deriv3(), deriv() etc. could be extended
to handle psigamma() and its special cases (digamma(), trigamma()
etc.). From the error message it seems that 'psigamma' needs to be
added to the derivatives table.
This might be easy since psigamma() has a deriv argument.
Additionally, this error message is also obtained when requesting for
the Hessian of
