as.data.frame.piar_index: Coerce an index into a tabular form

In piar: Price Index Aggregation

Coerce an index into a tabular form

Description

Turn an index into a data frame or a matrix.

Usage

## S3 method for class 'piar_index'
as.data.frame(
  x,
  row.names = NULL,
  optional = FALSE,
  ...,
  contrib = FALSE,
  stringsAsFactors = FALSE
)

## S3 method for class 'piar_index'
as.matrix(x, ...)

Arguments

x	A price index, as made by, e.g., elemental_index().
row.names, stringsAsFactors	See as.data.frame().
optional	Not currently used.
...	Not currently used.
contrib	Include percent-change contributions (the default does not include them).

Value

as.data.frame() returns the index values in x as a data frame with three columns: period, level, and value. If contrib = TRUE then there is a fourth (list) column contrib containing percent-change contributions.

as.matrix() returns the index values in x as a matrix with a row for each level and a column for each time period in x.

See Also

as_index() to coerce a matrix/data frame of index values into an index object.

index <- as_index(matrix(1:6, 2))
