`PLNnetworkfit`

object`R/PLNnetworkfit-S3methods.R`

`plot.PLNnetworkfit.Rd`

Extract and plot the network (partial correlation, support or inverse covariance) from a `PLNnetworkfit`

object

- x
an R6 object with class

`PLNnetworkfit`

- type
character. Value of the weight of the edges in the network, either "partial_cor" (partial correlation) or "support" (binary). Default is

`"partial_cor"`

.- output
the type of output used: either 'igraph' or 'corrplot'. Default is

`'igraph'`

.- edge.color
Length 2 color vector. Color for positive/negative edges. Default is

`c("#F8766D", "#00BFC4")`

. Only relevant for igraph output.- remove.isolated
if

`TRUE`

, isolated node are remove before plotting. Only relevant for igraph output.- node.labels
vector of character. The labels of the nodes. The default will use the column names ot the response matrix.

- layout
an optional igraph layout. Only relevant for igraph output.

- plot
logical. Should the final network be displayed or only sent back to the user. Default is

`TRUE`

.- ...
Not used (S3 compatibility).

Send back an invisible object (igraph or Matrix, depending on the output chosen) and optionally displays a graph (via igraph or corrplot for large ones)
