Hi R People:
Is there a way to put an abline line for its objects on a plot, please?
I have an its object, ibm2, which runs from the January 2 through May 28.
ibm2
ibm 2004-01-02 91.55 2004-01-05 93.05 2004-01-06 93.06 2004-01-07 92.78 2004-01-08 93.04 2004-01-09 91.21 2004-01-12 91.55 2004-01-13 89.70 2004-01-14 90.31 2004-01-15 94.02 . . . I plot the data. No Problem. Now I extract the first day of the month in this fashion.
zi <- extractIts(ibm2,weekday=T,find="first",period="month") zi
ibm 2004-01-02 91.55 2004-02-02 99.39 2004-03-01 97.04 2004-04-01 92.37 2004-05-03 88.02
Still ok. I would like to put a vertical line at each of the zi values.
abline(v=zi,type="h",col=2) lines(zi,type="h",col=2)
Nothing happens.
I tried creating another its object with NA in all but the zi places. Then I used lines(test1)
Still nothing happened.
Any suggestions would be much appreciated. R Version 1.9.1 Sincerely, Laura H mailto: [EMAIL PROTECTED]
