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)
