Dear all,

I  try to use read.table to get the data from a tab delimited file, and some
of the data is shown below:

3185    heterogeneous nuclear ribonucleoprotein F
3187    heterogeneous nuclear ribonucleoprotein H1 (H)
3188    heterogeneous nuclear ribonucleoprotein H2 (H')
3189    heterogeneous nuclear ribonucleoprotein H3 (2H9)
3190    heterogeneous nuclear ribonucleoprotein K /// heterogeneous nuclear
ribonucleoprotein K
3190    heterogeneous nuclear ribonucleoprotein K
3309    "heat shock 70kDa protein 5 (glucose-regulated protein, 78kDa)"
3310    heat shock 70kDa protein 6 (HSP70B')
3312    heat shock 70kDa protein 8
3313    heat shock 70kDa protein 9B (mortalin-2)
6302    sarcoma amplified sequence
6303    spermidine/spermine N1-acetyltransferase
6304    special AT-rich sequence binding protein 1 (binds to nuclear
matrix/scaffold-associating DNA's)
6305    SET binding factor 1
6307    sterol-C4-methyl oxidase-like
6625    Small nuclear ribonucleoprotein 70kDa polypeptide (RNP antigen)
6626    small nuclear ribonucleoprotein polypeptide A
6627    small nuclear ribonucleoprotein polypeptide A'
6628    small nuclear ribonucleoprotein polypeptides B and B1
6629    Small nuclear ribonucleoprotein polypeptide B''

when I use
> test <- read.table("data.txt", colClasses = "character", sep="\t")

I found out that "test" only has certain records:

3185    heterogeneous nuclear ribonucleoprotein F
3187    heterogeneous nuclear ribonucleoprotein H1 (H)
3188    heterogeneous nuclear ribonucleoprotein H2 (H')
3312    heat shock 70kDa protein 8
3313    heat shock 70kDa protein 9B (mortalin-2)
6302    sarcoma amplified sequence
6303    spermidine/spermine N1-acetyltransferase
6304    special AT-rich sequence binding protein 1 (binds to nuclear
matrix/scaffold-associating DNA's)
6628    small nuclear ribonucleoprotein polypeptides B and B1
6629    Small nuclear ribonucleoprotein polypeptide B''

and it means that whenever read.table reads  '  , it skips the next line,
until it reads  '   again....

Could anyone  show me how to solve this kind of problem ?

I greatly appreciate for any suggestion.  Thanks.
