[R] period in scale parameter of prcomp

[Greg Hirson]

Hi all,

Looking at the help file for prcomp and the code in
stats:::prcomp.default, the scale parameter for the default S3 method
has a trailing period: it written as

scale.

I assume there is a reason for it (backwards compatibility with S was
suggested) but I thought I'd ask.

Thanks,
Greg
