Subject: cm.colors bug (PR#244)

cm.colors() returns an extra element "1":

> cm.colors(10)
                                                                               

"#7FFFFF" "#99FFFF" "#B2FFFF" "#CCFFFF" "#E5FFFF" "#FFE5FF" "#FFCCFF" "#FFB2FF"

                            v 
"#FF99FF" "#FF7FFF"       "1" 
> 

Why I think it happens

The function has an unnecessary right parentheses
immediately preceding ", v=1" which causes the "v=1" to
be added to the vector rather than being interpreted as an
argument to hsv().

> cm.colors
function (n) 
{
    k <- n%/%2
    if (2 * k == n) {
        c(hsv(h = 6/12, s = seq(0.5, 0, length = k + 1)[-k - 
            1], v = 1), hsv(h = 10/12, s = seq(0, 0.5, length = n - 
            k + 1)[-1]), v = 1)
    }
    else {
        c(hsv(h = 6/12, s = seq(0.5, 0, length = k + 1), v = 1), 
            hsv(h = 10/12, s = seq(0, 0.5, length = n - k)[-1]), 
            v = 1)
    }
}
