you probably need to split your file into several files according to
the format. you can use something like perl or do it within R by doing
readline and then separating the lines. you can use grep, split and
textConnection to do most of the work.
What is the problem you are trying to solve?

Thanks David, but can read.fwf cope with different record types?
For example, if recordtype is the 4th character, I could have:
011125678 ---> This is record Type 1
011136779 ---> This is record Type 1
011124943 ---> This is record Type 1
011286711 ---> This is record Type 2
011234872 ---> This is record Type 2
011135628 ---> This is record Type 1
So, how can I tell read.fwf to take the correct type into account?
Thanks again,
Hug

I need to import several ascii files in fixed format with two
different record types. The data comes from European Labor Force
Surveys, wich is a household survey. The first record type is for
people over 16 years, and the second much sorter is for people aged
15 or less (this record has a filler with several blanks to get the
same record length).
The files tipically have 160000 records, with 176 characters per
record, the data is numeric, corresponding to 102 variables, mostly
integers (seven variables have two decimals). My opertating system
is Windows XP.
My questions:
1. Wich do you think is the best way to import the files into R?
?read.fwf
2. Could you give me any references or examples?
There are examples in the help page.
Thanking you in advance,
Hug
