Upananda,
I don't know your fut data, next time would help a simple dput(fut). Taking
into account the error message check the following:
library(PerformanceAnalytics)
df <- data.frame( sample(10)/100+100, seq(as.Date("2014-10-22"),
as.Date("2014-10-31"), by="day"))
str(df)
Return.calculate(df, "log")
#Error en checkData(prices, 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'.
df <- data.frame( sample(10)/100+100, row.names=seq(as.Date("2014-10-22"),
as.Date("2014-10-31"), by="day"))
str(df)
Return.calculate(df, "log")
df <- xts( sample(10)/100+100, order.by=seq(as.Date("2014-10-22"),
as.Date("2014-10-31"), by="day"))
str(df)
Return.calculate(df, "log")
If you are going to use the PerformanceAnalytics package I highly recommend
you to checkl the xts package.
