Hi Rebecca,
Assuming that 'raw_data' is data.frame with first column as "raw_time:
You could convert the raw_time to date format by
as.Date("28FEB2002",format="%d%B%Y")
#[1] "2002-02-28"
In your data, it should be:
raw_data$raw_time<- as.Date(raw_time,format="%d%B%Y")
Could you just dput() a few lines of your dataset if this is not working?
Tx.
A.K.

Hello Arun,
My data shows that I do not have a date type of data:
summary(raw_data)
raw_time raw_acct raw_baln
28FEB2002: 1 Min. : 61714 Min. :117079835
28FEB2003: 1 1st Qu.: 75587 1st Qu.:158035150
28FEB2005: 1 Median :100234 Median :206906298
28FEB2006: 1 Mean : 96058 Mean :210550369
28FEB2007: 1 3rd Qu.:116908 3rd Qu.:263623782
28FEB2009: 1 Max. :121853 Max. :325290870
(Other) :127
>
How could I transfer the "raw_time" column to a date format, such as
summary(dateA)
Min. 1st Qu. Median Mean 3rd Qu. Max.
"2012-01-01" "2012-04-01" "2012-07-01" "2012-07-01" "2012-09-30" "2012-12-31"
Thanks very much!
Cheers,
Rebecca

Hi,
You could also try this:
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))
library(xts)
Anew<-as.xts(A[,-1],order.by=A[,1])
Bnew<-as.xts(B[,-1],order.by=B[,1])
res<-merge(Anew,Bnew)
res1<-res[complete.cases(res),]
library(zoo)
plot.zoo(res1)
plot.zoo(res)

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.
