I used R interpreter. I have found the solution. I changed ".get(0)" to ".first()", then the exception is gone (see the following code snippet in ZeppelinRDisplay.scala:71).
private def textDisplay(body: Element): RDisplay = { //RDisplay(body.getElementsByTag("p").get(0).html(), TEXT, SUCCESS) RDisplay(body.getElementsByTag("p").first().html(), TEXT, SUCCESS) } Regards, /afancy On Wed, May 18, 2016 at 8:23 PM, Vinay Shukla <vinayshu...@gmail.com> wrote: > What is your interpreter for this core?
