.NAME in .Fortran

Duncan:

I experimented by using ".NAME =" in a call to .Fortran()
in one of my packages and got the same error as Peter.
I am definitely (!) using R version 2.15.1.

Doing args(.Fortran) gives:

function (.NAME, ..., NAOK = FALSE, DUP = TRUE, PACKAGE, ENCODING)
NULL
<bytecode: 0x9e7762c>

If I replace ".NAME" by "name" in my call to .Fortran() everything works
smoothly.

Consequently:  It looks to me like there is a bug here.  An inconsistency
between .Fortran() and ".Primitive(".Fortran")" perhaps.

      cheers,

          Rolf

Hi all

I've been getting some emails from the R package maintainers that I need
to update some code in a CRAN packge that uses FORTRAN, to comply with
(not so recent) changes.  I've been a little busy...

I'm having trouble adjusting my code.  I hope someone can help.

The package was working fine, and a few R functions in my package had
lines like this:

tmp <- .Fortran( name="pdf", <other parameters here>)

and similar.  The "pdf" is the name of the FORTRAN subroutine being
called, of course.

When I replace that line with

tmp <- .Fortran( .NAME="pdf", <other parameters here>)


...the package then does not pass the checks.  The library package
builds
OK with no errors or warnings, and then during "R CMD check" the
examples
give this error:

out <- tweedie.profile( y~1, p.vec=seq(1.1, 1.9, length=9),
do.plot=TRUE)

I've had a search--including a read of the "Writing R Extensions" manual
on CRAN (I did read it, but interestingly a search of that document did
not reveal any instance of .NAME)--and I cannot see the problem.  It's
probably obvious.

Any help appreciated, even pointers to more info.

I suspect you are doing your checks with an old version, not with the
one listed below.  The first argument was called "name" until R 2.13.0
was released; at that point it was changed to ".NAME" (to prevent
conflicts with something or other).  It seems someone forgot to note
this in the NEWS file...

You can find which version did the checks by looking at the header in
the 00check.log file created during the check.  You could also follow
Rolf's advice and not name the first arg.
