use R namespace functions to make it easier to use existing R functions

[adalisan]

There is a slightly hacky way to make it simpler to use existing R packages with FlashR
say you want to override the parse function in package:base

parse=function(...){ 
    base::parse(...) 
} 
 # Find out where the function lives. 
  env <- as.environment( 'package:base' ) 

  # Crack the binding. 
  unlockBinding( 'parse', env ) 

  # Replace the function. 
  assignInNamespace( 'parse', function(...){ 
  
   # Your function here, or an object that contains it. 

   }, ns = 'base' ) 

  # Relock the binding. 
  lockBinding( 'parse', env ) 

similarly you can overload functions in stats package, etc.
It is probably not too difficult to test this for the simple mvrnorm example.
This hack is not recommended by R developers, but for FlashR users who probably don't want to go through all R code in packages they use , it's a workable solution
