[R] plotting 2 time series data on the same graph

[arun]

Hi,
One more possibility:
dateA<-seq.Date(as.Date("1jan2012",format="%d%b%Y"),as.Date("14Feb2013",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=cumsum(rnorm(411)))
 set.seed(25)
 B<-data.frame(dateB,value=cumsum(rnorm(275)))
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),]
#install.packages("xtsExtra", repos='http://r-forge.r-project.org')
library(xtsExtra)
plot(res,screens=1,main="Time Series")
plot(res1,col=c(1,3))
A.K.

Hello,

I forgot a third possibility


plot(as.ts(cbind(x, y)), plot.type = "single", col = 1:2)
