Unfortunately, due to the vexing complexities of academic style guides and the limitations of associated software packages, citing a non-standard name, such as Cher, Prince, or R Development Core Team can be problematic. Thankfully, I have discovered a simple trick in Word and EndNote that allows for the accurate automatic formatting of R citations. Note that this method was developed using Word 2011 and EndNote X4 for Mac. I am unaware of the differences between operating systems and software versions, but it is anticipated that this method will work for almost anyone.
The Intuitive, But Nonworking Way
If you were going to create your R record in EndNote, you would probably enter something like what is pictured below. In the name field, it makes sense to just type in R Development Core Team.
However, this is where things take an untimely turn. EndNote will try to interpret that peculiar name as a series of first, last, and middle names, which leads to inaccurate citations.
The Unintiuitive, But Working Way
This is where we basically need to trick EndNote into interpreting our R citation the proper way. All we have to do is add a comma after R Development Core Team in the name field.
This tells EndNote that R Core Development Team is a complete last name of an author that has no first name. Hence, EndNote uses what it has (a last name with no first name) in generating its citations.
Note: The official citation for R can be found by issuing the citation() command in the R console.
