A few suggestions:
- read.fwf function sounds like what you need, but I have never used it so I
am not sure
- use readLines and manually extract needed positions and convert them to

I hope all is well. I've gone through and searched just about all the manuals, faqs, contribs available on the data import/export process and have not found any answer to a specific question. Hopefully, I will be able to fall back upon the valuable expertise in mailing list. Here goes:

How can I import SPECIFIC columns of data in a fixed width file? E.g. I have a fwf with 40 variables ranging from 1 to 10 characters and at any given time, need only a few to analyze, like so:  <age: 2 char ><sex: 1 char><morning: 1 char><location: 3 char>......<family: 9 char><tagged: date>.......<weight at capture: 4 char><length at capture: 7 char>etc.
which looks something like:

In essence I am looking for functionality similar to the SAS pointer/informat method. I would appreciate any help anyone would be able to give!

Thanks so much for your help.
