R help - Jul 2004 - median filter

Dear R users,

Does anyone know if there's a median filter available in R?
I have a considerable amount of images as 256 by 256 matrices and want to 
smooth them with a 5x5 median filter. Until now I'm not lucky in searching 
the R-help list/files.

Thanks,

Hanneke

None that I'm aware of, but I believe there are C and Fortran codes floating
around on the 'Net that you can try to link to R.
