Hi,
Here's a patch to the readChar manual page (R-trunk as of today) that
better clarifies readChar's return value. It could use some work as I'd
also like to add some text about using nchar() to find the length of the
string that readchar() returns, but I'm unsure which of type="bytes" or
type="chars" to mention. Is it type="chars"?

- items read (which might be less than \code{length(nchars)}).
+ For \code{readChar}, a character vector of length 1 with the number

For \code{writeChar}, a raw vector (if \code{con} is a raw vector) or
invisibly \code{NULL}.
