R Documentation

Mixture visualization of a `PLNmixturefit` object

Description

Represent the result of the clustering either by coloring the individual in a two-dimension PCA factor map, or by representing the expected matrix of count reorder according to the clustering.

plot(x, type = c("pca", "matrix"), main = NULL, plot = TRUE, ...)

Arguments

`x`	an R6 object with class `PLNmixturefit`
`type`	character for the type of plot, either "pca", for or "matrix". Default is `"pca"`.

`plot`	logical. Should the plot be displayed or sent back as `ggplot` object
`...`	Not used (S3 compatibility).

Value

a ggplot graphic

Examples

data(trichoptera)
trichoptera <- prepare_data(trichoptera$Abundance, trichoptera$Covariate)
myPLN <- PLNmixture(Abundance ~ 1 + offset(log(Offset)),
           data = trichoptera, control_main = list(iterates = 0))  %>% getBestModel()
plot(myPLN, "pca")
plot(myPLN, "matrix")
