Dear S'ersPLUS!:
Many thanks to Thomas Schmugge, Prof. Brian Ripley and especially to Bob Henery
for fast response. Now I inderstand that the obstacle for transition from
binary
to JPG is that S_plus does not handle one-bite data (so far, of course!)
Therefore, I want to slightly simplify the task. I transform binary matrix
into
the 3-digits integer matrix outside S-plus (using, say, a FORTRAN module
launched from S-PLUS). How to proceed from this point?
What I need is an entirely automatic procedure without any keyboard
interventions (INPUT: a million of binary files, OUTPUT: a million of JPG(BMP?)
files)
I work with S+3.3/4.5 on Pentium2/400MGz/128RAM under W95/98
