I successfully downloaded and loaded the stockPortfolio and quadprog packages, but when I entered the following command I got an error:
returns <- getReturns(names(stocks), freq="week") Error in file(file, "rt") : cannot open the connection In addition: Warning message: In file(file, "rt") : cannot open: HTTP status was '404 Not Found' When I tried discovering the source of this error, it appears that the file has been temporarily moved to a new URL address. Iâm currently running Windows 8.1. Is there a fix for this? Sent from Windows Mail [[alternative HTML version deleted]]
