Sqldf in R node failing

KNIME Analytics Platform
1

I have a work flow where i am using R predictor and am calling sqldf statement (after installing and calling the necessary libraries)

library(RSQLite)
library(DBI)
library(RSQLite.extfuns)
library(sqldf) 
library(tcltk)
library(pls)

The node was working fine and now its giving me a following error message:

"Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class = "tclObj") : 
  [tcl] out of stack space (infinite loop?)."

Can some one help me understand what i am doing wrong or if i need to install new packages. I am using knime 2.9.3 verion.

Thanks

Hi Ramya, 

It looks like the tcltk library is running out of memory, or getting stuck in a loop.  Not necesarrily KNIME related, but if you provide a reproducible example of the problem, maybe once of us can suggest a solution/workaround. 

Cheers,

Aaron
