Contributed R Packages
Below is a list of all packages provided by project Special Mathematical Functions.
Important note for package binaries: RForge provides these binaries only for the most recent version of R, but not for older versions. In order to successfully install the packages provided on RForge, you have to switch to the most recent version of R or, alternatively, install from the package sources (.tar.gz).
Packages
Bessel  Computations and Approximations for Bessel Functions  
Computations for Bessel function for complex, real and partly mpfr (arbitrary precision) numbers; notably interfacing TOMS 644; approximations for large arguments, experiments, etc.  
Version: 0.62  Last change: 20240812 12:43:39+02  Rev.: 325  
Download: (.tar.gz)  (.zip)  Build status: Current  Stable Release: Get Bessel 0.61 from CRAN  
R install command:
install.packages("Bessel", repos="http://RForge.Rproject.org")  

DPQ  Density, Probability, Quantile (DPQ) Computations  
Computations for approximations and alternatives for the DPQ
(Density (pdf), Probability (cdf) and Quantile) functions for probability
distributions in R.
Primary focus is on (central and noncentral) beta, gamma and related
distributions such as the chisquared, F, and t.

For several distribution functions, provide functions implementing formulas from
Johnson, Kotz, and Kemp (1992)  
Version: 0.59  Last change: 20240823 22:53:22+02  Rev.: 334  
Download: (.tar.gz)  (.zip)  Build status: Current  Stable Release: Get DPQ 0.59 from CRAN  
R install command:
install.packages("DPQ", repos="http://RForge.Rproject.org")  

DPQmpfr  DPQ (Density, Probability, Quantile) Distribution Computations using MPFR  
An extension to the DPQ package with computations for DPQ (Density (pdf), Probability (cdf) and Quantile) functions, where the functions here partly use the Rmpfr package and hence the underlying MPFR and GMP C libraries.  
Version: 0.33  Last change: 20240819 14:45:47+02  Rev.: 327  
Download: (.tar.gz)  (.zip)  Build status: Current  Stable Release: Get DPQmpfr 0.33 from CRAN  
R install command:
install.packages("DPQmpfr", repos="http://RForge.Rproject.org")  

dcdflib  R Interface to Probability Distribution Function Library DCDFLIB  
An interface to Barry Browns distribution function library DCDFLIB, where the first .C() interface was autogenerated via perl scripts.  
Version: 0.71  Last change: 20180818 22:27:50+02  Rev.: 53  
Download: (.tar.gz)  (.zip)  Build status: Failed to build  
R install command:
install.packages("dcdflib", repos="http://RForge.Rproject.org")  

Build status codes
0  Current: the package is available for download. The corresponding package passed checks on the Linux and Windows platform without ERRORs.
1  Scheduled for build: the package has been recognized by the build system and provided in the staging area.
2  Building: the package has been sent to the build machines. It will be built and checked using the latest patched version of R. Note that it is included in a batch of several packages. Thus, this process will take some time to finish.
3  Failed to build: the package failed to build or did not pass the checks on the Linux and/or Windows platform. It is not made available since it does not meet the policies.
4  Conflicts: two or more packages of the same name exist. None of them will be built. Maintainers are asked to negotiate further actions.
5  Offline: the package is not available. The build system may be offline or the package maintainer did not trigger a rebuild (done e.g., via committing to the package repository).
If your package is not shown on this page or not building, then check the build system status report.
