PLNmixture | R Documentation |

Fit the mixture variants of the Poisson lognormal with a variational algorithm. Use the (g)lm syntax for model specification (covariates, offsets).

```
PLNmixture(formula, data, subset, clusters = 1:5, control = PLNmixture_param())
```

`formula` |
an object of class "formula": a symbolic description of the model to be fitted. |

`data` |
an optional data frame, list or environment (or object coercible by as.data.frame to a data frame) containing the variables in the model. If not found in data, the variables are taken from environment(formula), typically the environment from which lm is called. |

`subset` |
an optional vector specifying a subset of observations to be used in the fitting process. |

`clusters` |
a vector of integer containing the successive number of clusters (or components) to be considered |

`control` |
a list-like structure for controlling the optimization, with default generated by |

an R6 object with class `PLNmixturefamily`

, which contains
a collection of models with class `PLNmixturefit`

The classes `PLNmixturefamily`

, `PLNmixturefit`

and `PLNmixture_param()`
