Hi there, ~ sry for the late answer.. and thanks for the advice.
i'm using a different approach than the CRR model because i'm implementing a pricing algorithm for american options with transaction costs. i'm not sure if i should close this thread for now, because right now i'm trying to do a different approach facing other difficulties and any other question that may come up would not fit to the topic anymore. i might start a new thread regarding a current problem though. so thanks for all the help ^^ -- View this message in context: http://r.789695.n4.nabble.com/as-function-parameters-tp4620390p4631759.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
