Upon replying to this email, I took a look at 'write.csv()' and noticed
something interesting. I remember there being a discussion sometime in
the past about letting 'write.csv()' accept the 'row.names' argument.
However, I get the following error:
> write.csv(airquality, file = "myfile.csv", row.names = F)
Error in write.table(airquality, file = "myfile.csv", row.names = F,
col.names = NA, :
col.names = NA makes no sense when row.names = FALSE
>
In 'write.csv()' there is
rn <- Call$row.names
Call$col.names <- if (is.logical(rn) && !rn)
TRUE
but is.logical(rn) is always FALSE because even if 'row.names' is
specified (non-NULL), it is of class "name". Perhaps something like
rn <- eval(Call$row.names)
would suffice? I can't tell if that would break anything.
