Realized that I hadn't put in-game much information on what these do, so I figured this is a good enough place to put the info. "R"is going to stand for the Rank of the bonus/trap. These all take effect on Turn 1, and cannot be dispelled or cleansed by any ability. If a character is KO'd and then revived however, they will no longer have the effect.
