Vote count:

0




I created a time series with:



ts_0615391206 <- ts(demand_rev_0615391206$estimated_demand,
start=as.Date(min(demand_rev_0615391206$date),format = "d%/m%/Y%"),
end=as.Date(max(demand_rev_0615391206$date),format = "d%/m%/Y%"))
ts_0615391206
Time Series:
Start = 16125
End = 16318
Frequency = 1

When I plot the ts



plot.ts(ts_0615391206)


on x axis I see numbers (count of days since 1/1/1970 to date) instead of dates. Any idea how to fix that ?
