[R] plot two time series with different length and different starting point in one figure.

[arun]

Hi,

dateA<-seq.Date(as.Date("1jan2012",format="%d%b%Y"),as.Date("31Dec2012",format="%d%b%Y"),by="day")
 dateB<-seq.Date(as.Date("1Mar2012",format="%d%b%Y"),as.Date("30Nov2012",format="%d%b%Y"),by="day")
set.seed(15)
 A<-data.frame(dateA,value=sample(1:300,366,replace=TRUE))
 set.seed(25)
 B<-data.frame(dateB,value=sample(1:300,275,replace=TRUE))
res<-merge(A,B,by.x="dateA",by.y="dateB") #it works


A.K.

Hello Petr,

As the time series have the same column names, I got the error message like:


--------------------------------------------------------------------
> m1<-merge(A, B, by.x = "time", by.y = "balance")
Error in fix.by(by.x, x) : 'by' must specify uniquely valid column(s)
--------------------------------------------------------------------

To plot A and B in one plot is to compare the difference between them...

Any other thoughts?

Thanks,

Rebecca

Merge those 2 series.
