Take the negative of a vector

Very simple function that takes the negative of a vector, here so that idiom such as

coeffs(z)[gradesminus(z)%%2 != 0] %<>% minus

works as intended (this taken from Conj.clifford()).

Usage

minus(x)

Value

Returns a vector or disord

Arguments

x

Any vector or disord object
