[R] bug in read.table?

[Joerg Maeder]

Hello,

in the new Relase (1.4) i get a different (worser) result for read.table
with as.is=T: it crash!

Input file (t.txt, with a name, 5 character and a numeric column)
Name	short	kind	logable	use	save	lag
m	"mo"	"x"	"n"	"1"	"n"	0
Ptp	"PT"	"l"	"y"	"m"	"n"	0

R-Code
read.table('t.txt',header=T,row.names=1,as.is=T)

R-Output
