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 item
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.
