system.dataset.setValue
Takes a dataset and returns a new dataset with a one value altered. Datasets are immutable, so it is important to realize that this function does not actually set a value in the argument dataset. You'll need to do something with the new dataset that this function creates to achieve something useful.
system.dataset. setValue( dataset, rowIndex, columnName, value )
-
Parameters
Dataset dataset - The starting dataset. Will not be modified (datasets are immutable), but acts as the basis for the returned dataset.
int rowIndex - The index of the row to set the value at (starting at 0)
String columnName - The name of the column to set the value at. Case insensitive.
PyObject value - The new value for the specified row/column.
-
Returns
Dataset - A new dataset, with the new value set at the given location.
