| .select {StabPerf} | R Documentation |
Perform a given feature-selector on a subset of a dataset, returning a list of features
.select(indices, data, selector, fold=NA, s=NA, nr=NA)
indices |
A vector of indices describing a subset of data, that is NOT used for selecting the features |
data |
A dataset, for which feature-selection should be performed |
selector |
The expression, that processes the dataset (in data), returning a list on indices (the features) |
fold |
k-th cross-validation step, may be set to pass it to the selector |
s |
selector is the s-th selector out of a list, may be set to pass it to the selector |
nr |
nr-th repeat in sampling for this selector |
Takes the subset train_indices out of data and performs selector on the resulting dataset (provided in data).
features |
vector of features that is determined by selector |
