Dear lists,
I have two data frame,
data.frame1<-data.frame(date=c(2010-01-01, 2010-01-02, 2010-01-03, 2010-01-04, 2010-01-05,2010-01-06,2010-01-07), A=c(0.5,10,15,3,10,20,12) , B=c(1.5,1,1.5,3.2,10.5,9,12))
data.frame2<-data.frame(date=c(2010-01-03, 2010-01-07), A=c(25.5,45) , B=c(4,34.7))
Now I would like to compare them. But before, I have to have the same length of rows. Data.frame2 is aggregated values of data.frame1. However, the time interval is irregular. Could you help me how to do this?
thanks !
