Good day, It is implemented by the CRAN package multicon. The function is named popsd. But it does seem like something R should provide without creating a package dependency. -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia

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

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? Many

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/ folders of (compiled) package roots. When opening an example of these files in a text editor (?Bessel in GNU emacs), the file is displayed as follows: _^HB_^He_^Hs_^Hs_^He_^Hl_^H _^HF_^Hu_^Hn_^Hc_^Ht_^Hi_^Ho_^Hn_^Hs Bessel package:base

I have a small handheld pc having ARM process as a CPU. I installed debian and installed R using apt-get command. Everything worked great except for drawing even simple graphs x <- 1:10 plot(x) I got error messages 1: Nonfinite axis limits [GScale(nan,nan,1, .); log=0] 2: relative range of values = 9.0072e+15 * EPS, is small (axis 1). 3: Nonfinite axis limits

Previously I had managed to get R-0.99.0 to compile and pass the tests on a Debian Linux/Alpha 2.2 system by recompiling src/main/optim.c by hand omitting the -O2 flag. I just tried R-1.0.0 on a similarly configured machine, although not the same machine as before, and it compiled ok but failed the tests. This time it fails on bessel> x <- seq(0, 4, len = 501) bessel> plot(x, x, ylim

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.

Good day, The use of "rounding" also doesn't make sense. If The number is halfway between two integers, it is rounded to the nearest even integer. > round(2.5) [1] 2 -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia

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

Good day, I'd like to suggest the addition of an as.list method for a by object that actually returns a list of class "list". This would make it safer to do type-checking, because is.list also returns TRUE for a data.frame variable and using class(result) == "list" is an alternative that only returns TRUE for lists. It's also confusing initially that > class(x) [1]

Good day, I believe from the documentation that folders in R_LIBS should appear in the output of .libPaths, but they do not. The documentation contains "The library search path is initialized at startup from the environment variable R_LIBS ..." However, $ export R_LIBS=/users/stgrad/dario/tmp/ $ Rscript -e ".libPaths()" [1] "/dskh/nobackup/biostat/Bioconductor"

Good day, If the library path is changed with .libPaths, the command install.packages("/nb/dario/Biostrings_2.39.9.tar.gz", repos=NULL) fails with ** testing if installed package can be loaded Error : package ?S4Vectors? required by ?Biostrings? could not be found However, running library(S4Vectors) followed by sessionInfo() after the error shows that the package can indeed be

Good day, Could the documentation of graphics devices give some explanation of how big the bitmap limits are? For example, > png("Figure1A.png", h = 7, w = 7, res = 1000, units = "cm") Results in Error: unable to start png() device, but the help page of devices doesn't explain that there are any limits or how they are determined. The wording of the error message could

Good day, I'm trying the example cl <- makeCluster(2, type = "SOCK") from the makeCluster documentation and the R command prompt never returns. I am using a 32-bit Windows 10 computer. The problem doesn't happen on another 64-bit Windows 10 computer but does happen on another 32-bit Windows 7 computer. Can anyone reproduce it? Are there any other options that can be passed to

Good day, I have been unable to solve this issue. Do you get grainy fonts when running the test case plot(1:10, main = "abcedfghijklmnopqrstuvwxyz", cex.main = 4, cex.lab = 4, cex.axis = 4) What version of libcairo is on your system ? -------------------------------------- Dario Strbenac PhD Student University of Sydney Camperdown NSW 2050 Australia

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

Good day, If there's a library folder of the latest R packages and a particular package from it is loaded using the lib.loc option, the dependencies of that package are still attempted to be loaded from another folder of older packages specified by R_LIBS, which may cause errors about version requirements not being met. The documentation of the library function doesn't explain what the
