Arguments

A data object handler
query
An extra query with which to filter the results, e.g. constructed with genomicRangeQuery or lexicographicQuery
columns
A list of column names to include in the results. The row ID column "__id__" will be ignored.
starting
The starting row ID from which to begin returning results
limit
The maximum number of rows to return

Value

data frame of rows from the GTable with row names equal to their row IDs

Description

Returns a data frame containing rows from the referenced GTable. Note that if limit rows are returned, there may be more rows which satisfy your query. To retrieve all rows, either set the limit high enough or repeat this query by changing the starting argument to be equal to one more than the last row ID received until no more rows are received.
