Coercion from and to zoo
Methods for coercing "zoo" objects to other classes and
a generic function as.zoo for coercing objects to class "zoo".
as.zoo(x, ...)

Methods for coercing objects of class "zoo" to other classes
currently include: as.ts, as.matrix, as.vector,
as.data.frame, as.list (the latter also being available
for "ts" objects). Furthermore, fortify.zoo can transform "zoo"
series to "data.frame" including the time index and optionally melting a wide series
into a long data frame.
In the conversion between zoo and ts, the zooreg class is
always used.
as.zoo returns a zoo object.

## coercion to zoo:
## default method
as.zoo(rnorm(5))
## method for "ts" objects
as.zoo(ts(rnorm(5), start = 1981, freq = 12))
## coercion from zoo:
x.date <- as.POSIXct(paste("2003-", rep(1:4, 4:1), "-", sample(1:28, 10, replace = TRUE), sep = ""))
x <- zoo(matrix(rnorm(24), ncol = 2), x.date)
as.matrix(x)
as.vector(x)
as.data.frame(x)
as.list(x)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
