[R] print.data.frame : row.name = FALSE not having intendedeffect

[Steven McKinney]

Here's the current method for printing a data frame:


> print.data.frame
function (x, ..., digits = NULL, quote = FALSE, right = TRUE, 
    row.names = TRUE) 
{
    n <- length(row.names(x))
    if (length(x) == 0L) {
        cat("NULL data frame with", n, "rows\n")
    }
    else if (n == 0L) {
        print.default(names(x), quote = FALSE)
        cat("<0 rows> (or 0-length row.names)\n")
    }
    else {
        m <- as.matrix(format.data.frame(x, digits = digits, 
            na.encode = FALSE))
        if (!isTRUE(row.names)) 
            dimnames(m)[[1]] <- if (identical(row.names, FALSE)) 
                rep.int("", n)
            else row.names
        print(m, ..., quote = quote, right = right)
    }
    invisible(x)
}
<environment: namespace:base>
> 

so you can either set up your own copy of this
or make a matrix copy of your data frame (as
done in the function above) and set the row names
to ""

Never mind -- the answer is buried in my own question... I was looking
at documentation for version 2.7.2, and when I looked at the one for
2.6.2, I see the row.names option isn't in that release.

Any suggestions on how I can code around that in 2.6.2, so I don't
have to upgrade to 2.7.2 just yet?

Thanks,
Matt

It is from the wellspring of our despair and the places that we are
broken that we come to repair the world.
