Subject: BUG in format()? (PR#383)
Message-ID: <199912211639.RAA02470@pubhealth.ku.dk>



In RW0.651 and RW0.901,
I discovered some unexpected behaviour when I used as.matrix.data.frame()

> matrix('"', 2, 2)
     [,1] [,2]
[1,] "\"" "\""
[2,] "\"" "\""
> unclass(as.data.frame(matrix('"', 2, 2)))
$V1
[1] "\"" "\""

$V2
[1] "\"" "\""

attr(,"row.names")
[1] "1" "2"
> as.matrix(as.data.frame(matrix('"', 2, 2)))
  V1     V2
1 "\\\"" "\\\""
2 "\\\"" "\\\""


I traced it back to a call to format (probably .Internal(format, ...))

> format('"')
[1] "\\\""

> format('\\')
[1] "\\\\"

Same in format.char() but not in formatC()

This behaviour of format() is not intended, is it?
Regards


Jens
