data(harry_potter_support)networkDynamic object. The data collection is described by the authors as follows:
Contact between the 64 Hogwarts students was coded as peer support when one of the four types of peer support, described in Tardy's model, were found: 1) Student A supports student B emotionally, e.g., in Book 1: Harry, Ron and Hermione assure Neville that he is definitely a Gryffindor when he doubts he is not brave enough to be part of the house; 2) Student A gives students B instrumental help; e.g., in Book 1: Fred and George Weasley help Harry Potter to get his trunk into the compartment of the Hogwarts Express; 3) Student A gives student B certain information to help student B, e.g., in Book 1: Hermione Granger helps Harry Potter with his homework and; 4) Student A praises student B, e.g., in book 5: Terry Boot praises Hermione Granger, for doing a Protean Charm, which is advanced magic. Furthermore, two extra conditions regarding the context in which peer support appeared needed to be fulfilled as well.
First, contact between students was only coded if the peer support was offered voluntarily. Second, only interactions occurring between two living characters, attending Hogwarts at the same moment, were coded as peer support. Consequently, when dead characters reappeared in the books, interactions between these dead characters and living students were not coded. One example for such reappearance is Cedric Diggory's return at the end of book 4, when Cedric asks Harry to return his dead body to his parents. Furthermore, interactions with former or future Hogwarts students at a certain point in time were not included. For example, although Harry and Ginny met before Ginny attended Hogwarts, peer support relations between both characters were only coded when both students attended Hogwarts together.
