Activates a dataset within the mass dataset object for further analysis.
activate_mass_dataset(
.data,
what = c("sample_info", "variable_info", "expression_data", "annotation_table")
)A mass_dataset object.
A character string specifying which dataset to activate. The available options are:
"sample_info": Activates the sample information dataset.
"variable_info": Activates the variable information dataset.
"expression_data": Activates the expression data.
"annotation_table": Activates the annotation table.
By default, it activates the "sample_info" dataset.
Returns the mass_dataset object with the specified dataset activated.
This function allows users to activate a specific dataset within the
mass_dataset object. The activated dataset can be then used in subsequent
analysis steps.
