[R] How to create a time series object with time only (no date)

[ce]

Thanks Joshua,

Would you kindly explain if I have an xts array with different dates how I change all dates to 1970-01-01 without touching the time ? I tried with indexFormat without success. indexFormat(s) <- "1970-01-01 %H:%M:%S" . when I plot a graph it still shows original dates. 
ce

You cant create an xts object without a date in the index. If the date doesnt matter, you can just set it to 1970-01-01 (or any other day).
