Extract a dataset consisting of a subset of treatments/readers from a larger dataset
DfExtractDataset(dataset, trts, rdrs)
dataset |
The original dataset from which the subset is to be extracted |
trts |
A vector contains the indices of the treatments to be extracted. If this parameter is not supplied, all treatments are extracted. |
rdrs |
A vector contains the indices of the readers to be extracted. If this parameter is not supplied, all readers are extracted. |
Note that trts
and rdrs
are the vectors of indices
not IDs. For example, if the ID of the first reader is "0", the
corresponding value in trts
should be 1 not 0.
A dataset containing only the specified treatments and readers that were extracted from the original dataset

## first modality from an included ROC dataset
ds1 <- DfExtractDataset(dataset05, trts = 1, rdrs = 2)
## Extract the data of the first and third reader in all
## modality from the included ROC dataset
ds2 <- DfExtractDataset(dataset05, rdrs = c(1, 3))
