Model extraction from a collection of models

Model extraction from a collection of models

# S3 method for PLNPCAfamily
getModel(Robject, var, index = NULL)

getModel(Robject, var, index)

# S3 method for PLNmixturefamily
getModel(Robject, var, index = NULL)

# S3 method for Networkfamily
getModel(Robject, var, index = NULL)

# S3 method for PLNnetworkfamily
getModel(Robject, var, index = NULL)

# S3 method for ZIPLNnetworkfamily
getModel(Robject, var, index = NULL)

Arguments

Robject

an R6 object with class PLNPCAfamily or PLNnetworkfamily

var

value of the parameter (rank for PLNPCA, sparsity for PLNnetwork) that identifies the model to be extracted from the collection. If no exact match is found, the model with closest parameter value is returned with a warning.

index

Integer index of the model to be returned. Only the first value is taken into account.

Value

Sends back an object with class PLNPCAfit or PLNnetworkfit.

Methods (by class)

• getModel(PLNPCAfamily): Model extraction for PLNPCAfamily

• getModel(PLNmixturefamily): Model extraction for PLNmixturefamily

• getModel(Networkfamily): Model extraction for PLNnetworkfamily or ZIPLNnetworkfamily

• getModel(PLNnetworkfamily): Model extraction for PLNnetworkfamily

• getModel(ZIPLNnetworkfamily): Model extraction for ZIPLNnetworkfamily

Examples

if (FALSE) {
data(trichoptera)
trichoptera <- prepare_data(trichoptera$Abundance, trichoptera$Covariate)
myPCA <- PLNPCA(Abundance ~ 1 + offset(log(Offset)), data = trichoptera, ranks = 1:5)
myModel <- getModel(myPCA, 2)
}
