x <- fts(index=seq(from=Sys.Date(),by="months",length.out=24),data=1:24)
y <- fts(index=seq(from=Sys.Date(),by="months",length.out=12),data=13:24)
xx <- x[1:10,]
## intersection of dates is taken for Arith methods
xyp <- x + y
xys <- x - y
xym <- x * y
xyd <- x / y
xyg <- x > y
xyl <- x < y
cxy <- cbind(x,y)
rxy <- rbind(x,y)
print(x)
plot(x)
