[R-sig-finance] ts-plotting?

[ebashi]

Dear R users,
I have just started R and already fascinated by its power. As this is my first email, I want to thank you all in advance and appreciate your efforts for helping others.
 
I have a problem to plot Time in x-axis and as I was looking in email archives, I found out that other people also have had some problems with it before. To make it short and simple, I use the same examples in fBasics package, I imported IBM data as follow,   
 
> ## yahooImport -
> xmpBasics("\nNext: IBM Shares from Yahoo > ")
> # [test 19/20 century change 01-12-1999 -- 31-01-2000]
> IBM = yahooImport(
+ query = "s=IBM&a=11&b=1&c=1999&d=0&q=31&f=2000&z=IBM&x=.csv",
+ try = TRUE)
 
> if (!is.null(IBM)) print(IBM[1:6, ])
           Open   High    Low  Close   Volume Adj. Close*
19991201 102.56 104.44 102.25 103.42  5340000      100.15
19991202 103.44 106.31 103.37 105.27  6220800      101.94
19991203 109.81 112.87 107.94 111.87 14680500      108.33
19991206 113.00 116.50 112.50 116.00  9933000      112.33
19991207 117.00 119.19 115.44 116.62 11329500      112.93
19991208 116.25 121.00 115.50 118.28  8145300      114.54

 
the dates in the first column don't have header and I don't know what type of data they are. when I plot them as follow,
>tsPlot(IBM$Close)
 
the x-axis has the row number ( I want to have Time in the x-axis)
 
but when I use the example for the tsPlot from the fBasics which is as follows,
> tsPlot(IBM$Open)
> ## tsPlot -
> xmpBasics("\nStart: European Stock Markets > ")
> # Show multiple plot:
> par(mfrow = c(1, 1), cex = 0.7)
> data(EuStockMarkets)
> tsPlot(EuStockMarkets, gpars = list(col = c(2:4, 6)), labels = FALSE)
> title(main = "European Stock Markets")
      (this is how EuStockMarkets look like)
> if (!is.null(IBM)) print(EuStockMarkets[1:6, ])
          DAX    SMI    CAC   FTSE
 [1,] 1628.75 1678.1 1772.8 2443.6
 [2,] 1613.63 1688.5 1750.5 2460.2
 [3,] 1606.51 1678.6 1718.0 2448.2
 [4,] 1621.04 1684.1 1708.1 2470.4
 [5,] 1618.16 1686.6 1723.1 2484.7
 [6,] 1610.61 1671.6 1714.3 2466.8
 
on the x-axis I get actual time values,
I will appreciate it if someone help me regarding that and also clarify it for me what is the difference between these two type of data.
 
Sincerely Yours,
 
Arshia
