Dear R-devel list members,
What's the best current advice about writing Fortran code for use in R
packages? The Writing R Extensions manual still says that the .Fortran
interface is primarily intended for FORTRAN 77 code. In particular, are
there portability issues if I use Fortran 95 in a

On Sun,
Below is code that introduces a list comprehension syntax into R,
allowing expressions like:
.[ sin(x) ~ x - (0:11)/11 ]
[1] 0. 0.09078392 0.18081808 0.26935891 0.35567516 0.43905397

.[ .[x*y ~ x - 0:3] ~ y -
That seems quite nice.
Note that there has been some related code posted. See:
http://tolstoy.newcastle.edu.au/R/help/03b/6406.html
which discusses some R idioms for list comprehensions.
Also the gsubfn package has some functionality in this direction. We
preface any function with fn$ to allow
