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.

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.Yes, you do not use the ' as a quote, hence you have to remove it from the default setting of its meaning as a quote....
