R Model Writer

Writes an R model in a KNIME proprietary format to a file or to a remote location denoted by an URL. This model can later be read using the appropriate reader.

This node can access a variety of different file systems. More information about file handling in KNIME can be found in the official File Handling Guide.

Options

Output location

Select a file to store the R model. The location can be exposed as or automatically set via a path flow variable.

Create missing folders

Select if the folders of the selected output location should be created if they do not already exist. If this option is unchecked, the node will fail if a folder does not exist.

If exists

Specify the behavior of the node in case the output file already exists.

Fail: Will issue an error during the node's execution (to prevent unintentional overwrite).
Overwrite: Will replace any existing file.
