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

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?
