Hello
Let's say I have a multivariate zoo timeseries (synchronised automatic
loggers at different places):
library(zoo)
library(lattice)
library(latticeExtra)
x-zoo(data.frame(a=rnorm(100), c=rnorm(100), b=rnorm(100)),
seq(from=as.Date(2010-01-01), by=day, length.out=100))
and a dataframe
str(x) ; str(y) reveals
#zoo series ...
# ..$ : chr [1:3] a c b ## HERE
# Index: Date[1:100], format: 2010-01-01 2010-01-02 2010-01-03
2010-01-04 ...
#'data.frame':99 obs. of 3 variables:
# $ ID : Factor w/ 3 levels a,b,c: ## HERE
# ...
#'
So change the
2 matches
