R: Add Connected Line Segments to a Circular Plot

lines.circular {circular} | R Documentation

## Add Connected Line Segments to a Circular Plot

### Description

A method taking coordinates in a polar system and joining the corresponding points with line segments.

### Usage

    ## S3 method for class 'circular'
    lines(x, y, join = FALSE, nosort = FALSE, offset=1, shrink=1,
      plot.info = NULL, zero = NULL, rotation = NULL, modulo = NULL, ...)

### Arguments

`x` | a vector of class `circular`.
`y` | a vector with the same length as 'x'.
`join` | logical: if `TRUE` the first and the last values are joined by a line.
`nosort` | logical: if `TRUE` the data are not sorted before join them.
`offset` | the radius of the circle
`shrink` | parameter that controls the size of the plotted function. Default is 1.
`plot.info` | an object from another circular graphic function.
`zero` | the zero of the axis.
`rotation` | the rotation of the axis.
`modulo` | the modulo applied to 'x' before sorting.
`...` | graphical parameters passed to `lines.default`.

### Value

A list with information on the plot: zero, rotation and next.points.
