check_document_covariate_table(document_covariate_table,
  LDA_models = NULL, document_term_table = NULL)

Arguments

LDA_models	Reference LDA model list (class LDA_set) that includes as its first element a properly fitted LDA model with a gamma slot with the document-topic distribution.
document_term_table	Optional input for checking when LDA_models is NULL

Value

An error message is thrown if document_covariate_table is not proper, else NULL.

Examples

  data(rodents)
