[R] Import fixed-format ascii file with mixed record types

[trece por ciento]

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

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).
