[...] Just for the record, I can copy and paste your code -- and get errors of the type Error in na.omit(trades(rownames(s), s$Price, s$St)) : could not find function "trades" But as others have already pointed out, it is better to '?source' code, or to use an editor that can push code chunks directly to R. -- Enrico Schumann Lucerne, Switzerland http://enricoschumann.net ______________________________________________ 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.
