[Rd] read.table

Hi All,

I wonder if there should be one character for quote= in read.table, i.e.,

> args(read.table)
function (file, header = FALSE, sep = "", quote = "\"'", dec = ".",

I have a file containing the following lines,

08248-GOTERM    3'-phosphoadenosine 5'-phosphosulfate biosynthetic process
08279-GOTERM    3'-phosphoadenosine 5'-phosphosulfate binding
08494-GOTERM    'de novo' posttranslational protein folding
08712-GOTERM    ATP-dependent polyribonucleotide 5'-hydroxyl-kinase activity
08759-GOTERM    double-stranded DNA specific 5'-3' exodeoxyribonuclease activity
09127-GOTERM    'de novo' actin filament nucleation
09180-GOTERM    5'-tyrosyl-DNA phosphodiesterase activity
09282-GOTERM    deoxyribonucleoside 5'-monophosphate N-glycosidase activity
09330-GOTERM    3'-UTR-mediated mRNA stabilization
09355-GOTERM    histone pre-mRNA 3'end processing complex

which has two tab-delimited columns. I used read.table("",as.is=TRUE) and ended up with fewer lines so I have to use quote="" which also works if  any line contains only a singe double (") quote.
