The R data node can only connect to the R model node. The input script displays the data of the R model in the form of a table.

Connect a R model node, enter the script, select the R data node settings and display area contains four pages: configuration items, metadata, filter data, exploration data.

 

❖Configuration

The R data can directly reference the MODEL variable. You can also use col[["xxx"]] to pass in the value of the corresponding column in the dataset. xxx is the name of the column. You can also pass parameter values via param[["xxx"]]. xxx is the parameter name. For custom scripts, R returns the result of the last executed line of code as the return value. The product requires that the return value must be a list object that contains a number of return value columns, such as list (out1=a, out2=b), where out1,out2 are the names of the return value columns, and a and b are the columns for the corresponding return value columns. The value can be a constant or a vector.

❖Export to Database

Imports the node data into the table specified by the selected database.

 

❖Rename R Data Node

In the R data node's right-click menu, select "Rename" to rename the node.

 

❖Refresh R Data Node

In the R data node's right-click menu, select "Refresh" to update the synchronization data or parameter information.

 

❖Save as Composite Node

In the right-click menu of node, select "Save as composite node" to save the selected node as a combined node to realize multiplexing nodes. The parameters of the saved node are consistent with the original node.

 

❖Copy/Cut/Paste/Delete R Data Node

The R data node's right-click menu supports copy, cut, paste, and delete operations.

【Copy】 Copy R data node.

【Cut】Cut R data node.

【Paste】 After selecting copy, right-click on the canvas blank to paste and copy the R data node.

【Delete】 Click the node right-click menu to click Delete, or click the keyboard delete button to delete, to delete the input and output connections of nodes and nodes.
