I am using getYahooData from TTR to get daily data. When i do it standalone, it is fine. It also works fine inside my code. However, when i run code inside mtrace(), i always get the following error: Error in xts(cbind(adj[[1]], adj[[2]]), index(obj)): order.by requires an appropriate time-based object After a lot of hand wringing, it looks to me that it happens because index in xts masks index in package mvbutils. Is there any way to avoid this type of masking of objects? -- View this message in context: http://r.789695.n4.nabble.com/masking-of-objects-between-mtrace-and-getYahooData-tp2126151p2126151.html Sent from the R help mailing list archive at Nabble.com.
