Filter row numbers¶
Filter rows by row number.
Keeps or drops rows with specific row numbers, i.e. based on their 0-based, consecutive integer index.
Usage¶
The following are the step's expected inputs and outputs and their specific types.
filter_row_numbers(ds_in: dataset, {"param": value}) -> (ds_out: dataset)
where the object {"param": value} is optional in most cases and if present may contain any of the parameters described in the
corresponding section below.
Example¶
To keep only rows with index 0, 2 and 4 (the first, third and fifth row)
filter_row_numbers(ds, {"row_numbers": [0, 2, 4]}) -> (ds_filtered)
Inputs¶
ds_in: dataset
An input dataset to filter.
Outputs¶
ds_out: dataset
A new dataset containing the same columns as the input dataset but only those rows passing the filter condition.
Parameters¶
row_numbers: array[integer]
Ids of the rows to filter. Excepts either a single row (as a number) or a list of row numbers.
exclude: boolean = False
if true, selected rows will be excluded from the resulting dataset.
