[R] How do I create an object in the Global environment from a function

[Henrik Bengtsson]

Please note that help("<<-") says:

"The operators '<<-' and '->>' cause a search to made through the
     environment for an existing definition of the variable being
     assigned.  If such a variable is found (and its binding is not
     locked) then its value is redefined, otherwise assignment takes
     place in the global environment."

Thus, if you really want to make sure to assign it to the global
environment you should do:

  assign("b", value, envir=globalenv())
