Hi R,
I want to do some rolling correlations. But before, I searched for "?rollingCorrelation" and tried the example in it. But I was not successful. What could be the problem? Here is the code I tried: > library(zoo) > library(PerformanceAnalytics) > rollingCorrelation([EMAIL PROTECTED],1],[EMAIL PROTECTED],n=12) Error in inherits(object, "zoo") : object "manager.ts" not found BR, Shubha [[alternative HTML version deleted]] ______________________________________________ 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.
