Plotting zoo Objects with tinyplot

The approach is similar to that in autoplot.zoo (based on ggplot2) and uses fortify.zoo (with melt = TRUE) to convert the zoo object into a data frame and then uses a suitable formula to visiualize the series.

Usage

# S3 method for class 'zoo'
tinyplot(object, facet, type = "l",
    facet.args = list(free = TRUE), ylab = "", ...)

Details

Convenience interface for visualizing zoo objects with tinyplot.

Arguments

object

an object of class "zoo".

facet

specification of facet for tinyplot.formula. The default in the tinyplot method is to use facet = NULL for univariate series and facet = ~ Series for multivariate series.

type, facet.args, ylab, ...

further arguments passed to tinyplot.

Examples

if(require("tinyplot")) {
suppressWarnings(RNGversion("3.5.0"))
set.seed(1)

## example data
x.Date <- as.Date(paste(2003, 02, c(1, 3, 7, 9, 14), sep = "-"))
x <- zoo(rnorm(5), x.Date)
xlow <- x - runif(5)
xhigh <- x + runif(5)
z <- cbind(x, xlow, xhigh)

## univariate plotting
tinyplot(x)

## multivariate plotting in multiple or single panels
tinyplot(z)                    ## multiple without color/linetype with free scales
tinyplot(z, facet.args = NULL) ## multiple without color/linetype with same scale
tinyplot(z, facet = ~ Series)  ## multiple with series-dependent color/linetype
tinyplot(z, facet = NULL)      ## single with series-dependent color/linetype

## by hand with color/linetype and with/without facets
d <- fortify.zoo(z, melt = TRUE)
tinyplot(Value ~ Index | Series, data = d, type = "l")
tinyplot(Value ~ Index | Series, facet = "by", data = d, type = "l")
tinyplot(Value ~ Index | Series, facet = "by", data = d, type = "l", facet.args = list(free = TRUE))

## EuStockMarkets data (coerced from "ts")
eusm <- as.zoo(EuStockMarkets)
tinyplot(eusm)
tinytheme("clean2")
tinyplot(eusm, facet = NULL)
tinyplot(eusm, facet = ~ Series)
tinyplot(eusm, facet = ~ Series, facet.args = NULL)
tinytheme() ## reset
