Problem with Embedded R Execution: SQL Interface (ORE)

问题

I'm new to ORE and I'm expected to work with it. To fulfill this goal, I'm studying related documents and trying to implement and practice their samples and examples. In this regard, to practice an example of embedded r script , I've faced with an error by executing below script in SQL:

• first I created the script:

  begin sys.rqScriptCreate('Example6','function(){
      res <- 1:10
      plot( 1:100, rnorm(100), pch = 21,
            bg = "red", cex = 2 )
      res
      }');end;
  

• Then I ran it:

  select value from  table(rqEval( NULL ,'XML','Example6'));
  

As the result of executing, below output is returned:

A table of a row and a column with "(HUGECLOB)" as value

Now when I click on that value twice to show XML output, below error will display:

ORA-22922: nonexistent LOB value

I've being used this link:

Can anyone help me to solve this error?
