Returns a plot of the data density (histogram) with an overlaid cut point generated by a Gaussian mixture model

1 | ```
plot_cut_point(m, plot = TRUE, color = c("grayscale", "amerika", "wesanderson"))
``` |

`m` |
An object of class |

`plot` |
A logical argument for generating the plot. If FALSE, only the cut point value from the GMM is returned. If TRUE, histogram with the overlaid cut point is returned. Default is set to TRUE. |

`color` |
A vector of color options including "amerika" (from package |

Gaussian mixture models are often used to derive cut points, or lines of separation between clusters in feature space (See Benaglia et al. 2009 for more). The `plot_cut_point`

function plots data densities with the overlaid cut point (the mean of the calculated `mu`

) from `mixEM`

objects, which are GMM's fit using the `mixtools`

package.
