Each curve line segment is made up of two anchor points. When you make a curved line, each endpoint has a handle. The direction of the handle changes the direction of the line. As I change, and I'm using the direct select tool, it affects one angle or one point. Now to draw a line, you just click, drag, click, and drag.

Plot symbols and colours can be specified as vectors, to allow individual specification for each point. R uses recycling of vectors in this situation to determine the attributes for each point, i.e. if the length of the vector is less than the number of points, the vector is repeated and concatenated to match the number required.
