xyVector

Construct an xyVector Object

Create an object to represent a set of x-y pairs. The resulting object can be treated as a matrix or as a data frame or as a vector. When treated as a vector it reduces to the y component only.

The result of functions such as predict.spline is returned as an xyVector object so the x-values used to generate the y-positions are retained, say for purposes of generating plots.
