R: Tidy a(n) zoo object

tidy.zoo {broom}

R Documentation

Tidy a(n) zoo object

Description

Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies cross models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

Usage

## S3 method for class 'zoo'
tidy(x, ...)

Arguments

x

A zoo object such as those created by zoo::zoo().

...

Additional arguments. Not used. Needed to match generic signature only. Cautionary note: Misspelled arguments will be absorbed in ..., where they will be ignored. If the misspelled argument has a default value, the default value will be used. For example, if you pass conf.lvel = 0.9, all computation will proceed using conf.level = 0.95. Additionally, if you pass newdata = my_tibble to an augment() method that does not accept a newdata argument, it will use the default value for the data argument.

Value

A tibble::tibble with one row for each observation in the zoo time series and columns:

`index`	Index (usually date) for the zoo object
`series`	Name of the series
`value`	Value of the observation

Examples


library(zoo)
library(ggplot2)

set.seed(1071)

# data generated as shown in the zoo vignette
Z.index <- as.Date(sample(12450:12500, 10))
Z.data <- matrix(rnorm(30), ncol = 3)
colnames(Z.data) <- c("Aa", "Bb", "Cc")
Z <- zoo(Z.data, Z.index)

tidy(Z)

ggplot(tidy(Z), aes(index, value, color = series)) +
  geom_line()
  
ggplot(tidy(Z), aes(index, value)) +
  geom_line() +
  facet_wrap(~ series, ncol = 1)

Zrolled <- rollmean(Z, 5)
ggplot(tidy(Zrolled), aes(index, value, color = series)) +
  geom_line()
