snap {flowcatchR} | R Documentation

## Snap the features of the closest particle identified

### Description

This function combines all classes related to a single experiment in order to deliver a clickable feedback on one of the frames.

### Usage

    snap(
      raw.frames,
      binary.frames,
      particleset,
      trajectoryset,
      frameID = 1,
      infocol = "yellow",
      infocex = 1,
      showVelocity = FALSE
    )

### Arguments

`raw.frames` | A `Frames` object with the raw frames data
`binary.frames` | A `Frames` object with the preprocessed frames data
`particleset` | A `ParticleSet` object with the particles data
`trajectoryset` | A `TrajectorySet` object with the trajectories data
`frameID` | The ID of the frame to inspect
`infocol` | The color to use for plotting the contours and the information on the clicked particle
`infocex` | The numeric character expansion value as in `cex` to be used for printing the text on the image
`showVelocity` | Logical, whether to display additional information on the instantaneous velocity of the particle

### Value

An image of the selected frame, rendered in R native graphics, and additionally a list with the coordinates as well as the trajectory ID of the particle closest to the clicked location
