[Rd] scale

[Paul Gilbert]

Martin> Is it okay to require the center and scale argument for all
methods?

Unfortunately, no, not the way I have used it. (One of the ways I use it
is for a structure called TSdata that has two data matrices. I
eventually call the default with a center and scale for each matrix, but
the original call is scale(x, scale), where scale is a list with a
center and scale value for each matrix.) My methods always use the
argument scale, but not center.
