suppressWarnings(RNGversion("3.5.0")) set.seed(1) x.date <- as.Date(paste(2003, rep(1:4, 4:1), seq(1,20,2), sep = "-")) x <- zoo(matrix(rnorm(20), ncol = 2), x.date) ## the full time series x ## and only matrix of observations coredata(x) ## change the observations coredata(x) <- matrix(1:20, ncol = 2) x
