[R] writing to a fixed format (fortran) file

[Duncan Golicher]

Could anyone help with what should be a simple task? I have data as a 
fixed format (fortran) table. I  have no trouble getting it into R using 
read.table. Each column is separated by a space, including the first 
column that begins with a space, and aligned. It reads into R as if 
separated by tabs. However I want to manipulate two columns of data then 
write the results out into exactly the same fortran format for use in 
another program.  It should be simple, but I've tried a variety of 
experiments with print, cat and format, none of which have come close.

Here is a sample of the data.
