WARNING: Method convertPointFromBase

Hello,
I?ve noticed a Warning, while working with both the R console and a document window in R:
2016-05-23 22:16:17.507 R[2985:466607] *** WARNING: Method convertPointFromBase: in class NSView is deprecated on 10.7 and later. It should not be used in new applications. 

I have Version R 3.3.0 GUI 1.68 Mavericks build (7202) installed on my Macbook Pro running Mac OS X 10.11.5 (15F34).

Is this something to worry about? Can anyone help me out? 

I downloaded R from the official servers. 

Kind regards and thank you in advance  !
