[R] converting help files with Sd2Rd

[Fredrik Lundgren]

Dear list,

I would like to convert several .d files to several .Rd files
in cmd.exe (Win XP home):

R CMD Sd2Rd *.d
prints all files to the screen, I want the individual files saved to 
disk

R CMD Sd2Rd *.d > foo.Rd
puts them into one file, I want the individual files

R CMD Sd2Rd *.d > *.Rd
complains:
Wrong syntax for file name, directory name eller volyme etiquette.

R CMD Sd2Rd foo.d > foo.Rd
works OK


How can I transform several .d files to several  .Rd files with one 
command?

Best wishes Fredrik
