getDataset-methods {Rmagpie} | R Documentation |
This method provides an easy interface to access the attributes of a dataset
directly from an object assessment. The argument topic
specifies which part
of the dataset is of interest.
object |
Object of class assessment . Object assessment of interest |
topic |
character . Optional argument that specifies which attribute of
the dataset is requested, the possible values are
"dataId" (slot dataId of the dataset),
"dataPath" (slot dataPath of the dataset),
"geneExprFile" (slot geneExprFile of the dataset),
"classesFile" (slot classesFile of the dataset),
"eset" (slot eset of the dataset)
if the "topic" is missing then the whole dataset object is returned. |
The value returned by the method changes accordingly to the "topic"
argument.
If "topic"
is missing
object of class dataset
the dataset corresponding to the assessment of interest
If "topic"
is "dataId"
object of class character
corresponding to the dataId
of the dataset
If "topic"
is "dataPath"
object of class character
corresponding to the dataPath
of the dataset
If "topic"
is "geneExprFile"
object of class character
corresponding to the geneExprFile
of the dataset
If "topic"
is "classesFile"
object of class character
corresponding to the classesFile
of the dataset
If "topic"
is "eset"
object of class ExpressionSetOrNull
corresponding to the eset
of the dataset
