I am using IEEEtran as the bibliography style. I want to append a letter (e.g., R) to the citation within the text and at the end of the document.
I was able to solve the problem for the list of References. This is achieved by inserting
\makeatletter
\renewcommand\@biblabel[1]{[R#1]}
\makeatother
to my preample. So, now the list of References is as follows:
[R1] ...
[R2] ...
However, I cannot get it to work inside the text. To be more specific, I want my text to be as follows: "The authors in [R1] did ..." instead of "The authors in [1] did ...". Any suggestions?
