# Interpolates between two points

### Description

This function calculates intermediate points between two points. The intermidate points can be jittered and smoothed with a Bezier curve.

### Usage

1 2 | ```
pointssegment(xbegin, ybegin, xend, yend,
npoints = 10, xjitteramount= 0, yjitteramount=0, bezier = TRUE)
``` |

### Arguments

`xbegin` |
A numeric value. Coordinate x of the point from which to interpolate. |

`ybegin` |
A numeric value. Coordinate y of the point from which to interpolate. |

`xend` |
A numeric value. Coordinate x of the point to which to interpolate. |

`yend` |
A numeric value. Coordinate y of the point to which to interpolate. |

`npoints` |
Number of points (including the limits). |

`xjitteramount, yjitteramount` |
Numeric. Amount of jitter. |

`bezier` |
Logical. Use or not the Bezier curves to smooth the jittered data. |

### Details

It calculates the intermediate points between two points. If there are no jitter amounts, then there are no interpolations.

By default, the data are smoothed using a Bezier curve. It gives 30 points.

### Value

A data frame with the interpolated values.
