[R] Axe time of series in format yy-mm-dd

[Gabor Grothendieck]

get.hist.quote produces times relative to Dec 31, 1899, so try this:

require(tseries)
require(chron)

ibm <- get.hist.quote( "ibm", start = "2003-01-01", quote = "Close" )

time.ibm <- chron( time(ibm), out.format="y-m-d", 
   origin = c( month = 12, day = 31, year = 1899 ) )
plot( time.ibm, ibm, type="l", simplify = F )

The simplify=F flag on plot forces the year to appear.  Without
it, only the month and day are displayed.

I'm trying to plot a ibm stock time series.
I made the download of that series,
ibm <- get.hist.quote(instrument = "ibm", start = "2003-01-01",quote=c("CL"))
And ibm is a serie wiht this characteristic:
Start = 37623 
End = 37960 
Frequency = 1 
When I try to plot it,
ts.plot(ibm)
In the graphic the axe time is represented by 37623 ... 37960, How can I put the time in the format,
yy-mm-dd ?

Thanks a lot
