Dear all, I am trying to clean return data using the Return.clean() function in the PerformanceAnalytics package. Hence, my code looks as follows but I get an error message.
cleantest <- read.csv("D:/Studie_vola_difference/cleantest.csv") data<-as.vector(cleantest) test<-Return.clean(data,method="boudt",alpha=0.01) Error in checkData(R, method = "xts") : The data cannot be converted into a time series. If you are trying to pass in names from a data object with one column, you should use the form 'data[rows, columns, drop = FALSE]'. Rownames should have standard date formats, such as '1985-03-15'. Can anybody help me on this error? What is wrong with my code? Thanks for your support.
