Reading data file with both fixed and tab-delimited fields
...at ftp://ftp.bls.gov/pub/time.series/la/, and the data are
documented in the file la.txt
<ftp://ftp.bls.gov/pub/time.series/la/la.txt>. Each data file has five
tab-delimited fields:
* series_id
* year
* period (codes for things like quarter or month of year)
* value
* footnote_codes
The series_id consists of five fixed-width subfields (length in
parentheses):
* survey abbreviation (2)
* seasonal code (1)
* area type code (2)
* area code (6)
* measure code (2)
So an example record might be:
LASPS36040003 1990 M01 8.8 L
I want to read in the data in one...

How to set a filter during reading tables
We are reading big tables, such as,
Chemicals <-
read.table('ftp://ftp.bls.gov/pub/time.series/wp/wp.data.7.Chemicals',header
= TRUE, sep = '\t', as.is =T)
I was wondering if it is possible to set a filter during loading so that
we just load what we want not the whole table each time. Thanks,
