Import ASCII data using a .sas program
...es involved and the ASCII data file is 2308 columns long so I
would certainly prefer to figure out a smart way of converting the data
to R.
The ASCII data is a long stream of numbers (no field separators or
delimiters) while the SAS import file looks like:
libname mine 'c:\';
data mine.fh4;
infile 'd:\fh4.txt' lrecl=2309;
input
perstat1 $1-2
linenum $3-4
I_wave1 $5-5
bnocost1 $6-10
bnosta1 $11-12
So SAS uses the position of the ASCII character to determine what
variable the data should be in while the SCAN or the READ. FWF function
of R uses the width o...

Since it looks like ReadFileScatter() does some of that work
automatically (in page file sized chunks), I thought I''d give it a try.
Here''s what I''ve got, but it doesn''t work. I have an incorrect parameter
