Dear Christian,
Well... it shouldn't normally do that. The only way I can currently
think of that might cause this problem is that the file has \r\n\r\n,
which would mean that every line is followed by an empty line.
Another cause might be (although I would not really expect the results
you see) that the sum of your column widths is larger than the actual
with of the line.
You can check your line lengths using:
lines <- readLines(my.filename)
nchar(lines)
Each line should have the same length and be equal to (or at least
larger than) sum(my.column.widths)
If this is not the problem: would it be possible that you send me a
small part of your file so that I could try to reproduce the problem? Or
if you cannot share your data: replace the actual values with nonsense
values.
Regards,
Jan
PS I read your mail by chance as I am not a regular r-help reader. When
you have specific LaF problems it is better to also cc me directly.

Dear all
I was trying the (fairly new) LaF package, and came across the following
problem:
I opened a connection to a fixed width ASCII file using
laf_open_fwf(my.filename, my.column_types, my.column_widths, my.column_names)
When looking at the data, it turned out that \n (newline) and \r (carriage
return) were considered as characters, thus destroying the structure in my data
(the second column does not include any numbers):
my.data[1565:1575,1:3]
MF_FARZ1 Fahrzeugarttext MF_MARKE

I am working on Windows 7 32-bit.
Any help would be highly appreciated.
