Since long, coordinate reference systems in R (and many other tools) have been represented by so called ‘PROJ.4 strings’ (or ‘proj4strings’), referring to the long-standing version 4 of the PROJ library. WebPoints and Vectors Basic Definitions. A scalar represents magnitude, and is given by a real number: .. A point in n-dimensional space is given by an n-tuple where each coordinate p i is a scalar number. We will write as a shorthand for this n-tuple. The position of a point is relative to a coordinate system with an origin and unit axes , , ..., and. Thus, a 3 …
