Subject: [Rd] file.info()$isdir is not TRUE (PR#1439)
Message-ID: <200204061050.MAA12036@pubhealth.ku.dk>

R -vanilla

> info <- file.info("C:/Windows/regedit.exe")
> info$isdir
[1] FALSE
> info$isdir == FALSE
[1] TRUE

But:

> info <- file.info("C:/Windows")
> info$isdir
[1]TRUE           <<< Note the missing space!
> info$isdir == TRUE
[1] FALSE
> is.logical(info$isdir)
[1] TRUE
> as.logical(info$isdir) == TRUE
[1] FALSE
> as.logical(as.character(info$isdir)) == TRUE
[1] TRUE

I get the same behaviour on Solaris 8.

Best
