| selectByLabel {GCDkit} | R Documentation |
Selecting subsets of the data stored in memory by searching sample names or a single label.
selectByLabel()
This function enables the user to query a single textual column, a label,
chosen using the function 'selectColumnLabel'.
The current data will be replaced by its newly chosen subset.
These enquiries employ regular expressions.
Overwrites the data frame 'labels' and numeric matrix 'WR' by
subset that fulfills the search criteria.
