Thank you for replying the as.Date error question.
I have one more question as below.
I used cbind command, and data x changed, 2010-11-16 to 14929, 2010-11-17 to
14930.
What happened to them?
What should I do to see yyyy-mm-dd format data?
> x=c("11/16/2010","11/17/2010","11/18/2010","11/19/2010")
> x=as.Date(x,"%m/%d/%Y")
> x
[1] "2010-11-16" "2010-11-17" "2010-11-18" "2010-11-19"
> y=c(1753.75,15077,1759.35,15078)
> cbind(x,y)
x y
[1,] 14929 1753.75
[2,] 14930 15077.00
[3,] 14931 1759.35
[4,] 14932 15078.00
Thanks
