RenameDocs

Renames the specified columns keeping their original values and location within the DataFrame.

This function does not immediately rename the columns but instead selects columns to rename and returns a RenameClause, which serves as an intermediate step. The RenameClause object provides methods to rename selected columns using:

• to(name) - renames selected columns to the specified names.

• to { nameExpression } - renames selected columns using a provided expression assuming column with its path and returning a new name.

• toCamelCase() - renames all selected columns to "camelCase".

Each method returns a new DataFrame with the renamed columns.

Check out Grammar.

This can include column groups and nested columns.

See Selecting Columns.

For more information: See rename on the documentation website.

See also renameToCamelCase which renames all columns to "camelCase" format.
