Hi, I got the following message when I used the getReturns in the fMultivar package. (it worked fine in previous version of fSeries). > data(EuStockMarkets) > dax = log(EuStockMarkets[, "DAX"]) > plot(getReturns(dax)) Error in ans[-1, ] : incorrect number of dimensions Appreciate any help. Thanks. Sanjun Chen
