[R-pkg-devel] incomplete gamma function Fortran subroutine

Hello, In an R function within a package, I would like to call a Fortran subroutine to compute lower gamma function. Any advice will be appreciated. Thanks! Zhu Wang [[alternative HTML version deleted]] __ R-package-devel@r-project.org

Re: [R-pkg-devel] incomplete gamma function Fortran subroutine

Sorry for not making myself clear: The Fortran subroutine in an R package needs to call incomplete gamma function. -Original Message- From: R-package-devel On Behalf Of Ben Bolker Sent: Tuesday, July 21, 2020 12:54 PM To: r-package-devel@r-project.org Subject: Re: [R-pkg-devel]

BTW, if you search for "incomplete gamma function" on Rseek.org, you will find whole packages for this. Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Tue,

Why? -- see ?dgamma See also the section on including fortran code in "Writing R Extensions," which should be your first port of call for such questions. If neither of these is what you need, it may be helpful if you explain why not. Bert Gunter "The trouble with having an open mind is that

    Is there a reason not to use pgamma(), possibly adjusted by a (de-)normalizing constant?   (See detailed notes in ?pgamma) On 7/21/20 1:44 PM, Wang, Zhu wrote: Hello, In an R function within a package, I would like to call a Fortran subroutine to compute lower gamma function. Any advice

  Interesting.  It looks like the way to make use of this is to combine the information in section 6.7.1 ("Distribution functions", including pgamma ...) with section 6.6 "Calling C from Fortran and vice versa" ? On 7/21/20 4:33 PM, luke-tier...@uiowa.edu wrote: Looking at this section of WRE

As others have said, built-in function pgamma is a (normalized) version of the incomplete gamma function! John -Original Message- From: R-package-devel On Behalf Of Wang, Zhu Sent: Tuesday, July 21, 2020 2:16 PM To: Ben Bolker ; r-package-devel@r-project.org Subject: Re:

You can often find this kind of code on netlib.org. Just include it with the fortran code in your package. On Tue, Jul 21, 2020 at 11:22 AM Wang, Zhu wrote: > Sorry for not making myself clear: The Fortran subroutine in an R package > needs to call incomplete gamma function. > > -Original

Thanks to Ben and John. Perhaps the program should call pgamma in R and pass the number to Fortran. Calling some Fortran subroutines older than R can trigger concerns when submitting the package to the CRAN. Best, Zhu -Original Message- From: John P. Nolan Sent: Tuesday, July 21,

HelloYesterday a new version of cartograflow v1.0.3 was updated on the crank.  Everything seems to be OK. However, when I write in help cartograflow I don't see the thumbnail with the different possibilities of visualization: pdf, HTML ... Is this normal? Thank you in advance for your answer
