Index Stat

Convert a time series from the original scale to an index for ggplot2

Usage
stat_index(mapping = NULL, data = NULL, geom = "line", position = "identity", show.legend = NA, inherit.aes = TRUE, index.ref = NULL, index.basis = 100, ...)
Arguments
mapping
Set of aesthetic mappings created by aes or aes_. If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.
data
The data to be displayed in this layer. There are three options:

If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot.

A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify for which variables will be created.

A function will be called with a single argument, the plot data. The return value must be a data.frame., and will be used as the layer data.

geom
The geometric object to use display the data
position
Position adjustment, either as a string, or the result of a call to a position adjustment function.
show.legend
logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.
inherit.aes
If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders.
index.ref
if not NULL, a vector of integers indicating which elements of the beginning of each series to use as a reference point for converting to an index. If NULL, no conversion takes place and the data are presented on the original scale.
index.basis
if index.ref is not NULL, the basis point for converting to an index, most commonly 100 or 1000. See examples.
