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.
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....
Best,
Uwe Ligges
Thanks,
