Is there a function in R to get the set of all unit vectors which are
orthogonal to a given vector?
No.
Building blocks should be there, though. The last n-1 columns of
Q <- qr.Q(qr(cbind(v, diag(nrow=length(v)))))
looks like a good start.
The full set is an n-1 dimensional sphere in n-space, spanned by those column
vectors. If you need more than that representation, some further assembly is
required.
