Dates [ numeric ] - Dates for which observations will be supplied; dates do not have to be sorted in ascending order. If dates is scalar and values have multiple rows, then the date in dates is interpreted as a startdate for the time series.
Values [ numeric | function_handle ] - Numerical values (observations) arranged columnwise, or a function that will be used to create an N-by-1 array of values, where N is the number of dates.
Comment [ char | cellstr ] - Comment or comments attached to each column of observations.
X [ tseries ] - New tseries object.
