ivwdataframe.appendColumns(left: ivwdataframe.DataFrame, right: ivwdataframe.DataFrame, ignoreDuplicates: bool = False, fillMissingRows: bool = False) → ivwdataframe.DataFrame

Create a new DataFrame by appending the columns of DataFrame right to DataFrame left

Parameters:

ignoreDuplicates – duplicate columns, i.e. same column header, are ignored if true
fillMissingRows – if true, missing rows in either DataFrame are filled with 0 or “undefined” (for categorical columns)

ivwdataframe.appendRows(top: ivwdataframe.DataFrame, bottom: ivwdataframe.DataFrame, matchByName: bool = False) → ivwdataframe.DataFrame

Create a new DataFrame by appending the rows of DataFrame bottom to DataFrame top

Parameters:: matchByName – if true, column headers are used for matching columns. Otherwise columns are matched by order (default)

ivwdataframe.innerJoin(*args, **kwargs)

Overloaded function.

innerJoin(left: ivwdataframe.DataFrame, right: ivwdataframe.DataFrame, keyColumn: tuple[str, str] = ‘index’) -> ivwdataframe.DataFrame

Create a new DataFrame by using an inner join of DataFrame left and DataFrame right. That is only rows with matching keys are kept.

It is assumed that the entries in the key columns are unique. Otherwise results are undefined.

Args:

keyColumn: header of the column used as key for the join operation
(default: index column)
innerJoin(left: ivwdataframe.DataFrame, right: ivwdataframe.DataFrame, keyColumn: list[tuple[str, str]]) -> ivwdataframe.DataFrame

Create a new DataFrame by using an inner join of DataFrame left and DataFrame right. That is only rows with matching all keys are kept.

It is assumed that the entries in the key columns are unique. Otherwise results are undefined.

Args:
keyColumn: list of headers of the columns used as key for the join operation
innerJoin(left: ivwdataframe.DataFrame, right: ivwdataframe.DataFrame, keyColumn: tuple[str, str] = ‘index’) -> ivwdataframe.DataFrame

Create a new DataFrame by using an outer left join of DataFrame left and DataFrame right. That is all rows of left are augmented with matching rows from right.

It is assumed that the entries in the key columns of right are unique. Otherwise results are undefined.

Args:

keyColumn: header of the column used as key for the join operation
(default: index column)

ivwdataframe.leftJoin(left: ivwdataframe.DataFrame, right: ivwdataframe.DataFrame, keyColumn: list[tuple[str, str]]) → ivwdataframe.DataFrame

Create a new DataFrame by using an outer left join of DataFrame left and DataFrame right. That is all rows of left are augmented with matching rows from right.

It is assumed that the entries in the key columns of right are unique. Otherwise results are undefined.

Parameters:: keyColumn – list of headers of the columns used as key for the join operation
