My version would be

  newDev <-  function() { dev.new(); invisible( dev.cur() ) }

I agree with Hadley that return() is redundant in this instance. Using invisible() suppresses automatic printing of the returned value when it is not being assigned to a variable, thus making it more like dev.new().

While we're at it, consider

  newDev <-  function(...) { dev.new(...); invisible( dev.cur() ) }

which should allow one to pass through optional arguments (which only makes sense if they're valid for dev.new(), of course).

 You could wrap it in a function of your own making, right?

 AddNewDev = function() {dev.new();AddNewDev=dev.cur()}

 histPlot=AddNewDev()

 Seems to work.

  You leaRn fast :) Probably better style is:

 >  newDev = function(){dev.new();return(dev.cur())}

  - which returns the value explicitly with return().

R isn't C! ;)  I'd claim idiomatic R only uses return for special
cases (i.e. when you can terminate the function early)
