Plot Log-Ratios

Source: R/AllGenerics.R, R/plot.R
plot_logratio.Rd

Displays a compositional bar chart.

Usage

# S4 method for LogRatio
autoplot(object, ..., order = FALSE, decreasing = FALSE, facet = TRUE)

# S4 method for LogRatio,missing
plot(x, order = FALSE, decreasing = FALSE, facet = TRUE, ...)

Arguments

...

Currently not used.

order

A logical scalar: should the ratio be ordered?

decreasing

A logical scalar: should the sort order be increasing or decreasing?

facet

A logical scalar: should a matrix of panels defined by groups be drawn? Only used if x has groups defined.

x, object

A CompositionMatrix object.

Value

  • autoplot() returns a ggplot object.

  • plot() is called it for its side-effects: it results in a graphic being displayed (invisibly returns x).

Examples

## Coerce to compositional data
data("hongite")
coda <- as_composition(hongite)

## Bar plot
plot(coda, order = 2)


## Use ceramic types for grouping
data("kommos", package = "folio")
kommos <- remove_NA(kommos, margin = 1) # Remove cases with missing values
coda <- as_composition(kommos, groups = 1)
#> 1 qualitative variable was removed: date.

plot(coda, order = 1)


## Log ratio
clr <- transform_clr(coda)
plot(clr, facet = FALSE)
