Hello, I need to put 2 or more different time series to one plot for comparison each other. The problem is that the time series are irregular, moreover the time lenghts and periods are not the same. Is there a way to manage it in R? Many thanks for any hint and advice in advance Tomas
plot.zoo and xyplot.zoo in the zoo package can both do that:
library(zoo)
z <- zoo(c(21, 34, 33, 41, 39, 38, 37, 28, 33, 40),
as.Date(c("1992-01-10", "1992-01-17",
"1992-01-24", "1992-01-31",
"1992-02-07", "1992-02-14", "1992-02-21",
"1992-02-28", "1992-03-06",
"1992-03-13")))
# z and lag(z) have different spans and are irregular
zz <- merge(z, lag(z))
# same screem
plot(zz, screen = 1)
# different screens
plot(zz)
# similar but using zoo's xyplot lattice method
library(lattice)
xyplot(zz, screen = 1)
xyplot(zz)
Read the three vignettes that come with zoo and the help files.

You need to have both series in a single mts object. Look also at the argument plot.type...
