Inflate using a general index

Inflate using a general index

inflator(x = 1, from, to, inflator_table, index.col = "Index",
  time.col = "Time", roll = NULL, max.length = NULL)

Arguments

x	The vector to be inflated.
from	The contemporaneous time of x.
to	The target time (in units of the inflator_table) to which x is to be inflated.
inflator_table	A data.table having columns index.col and time.col.
index.col	The column in inflator_table containing the index used for inflation.
time.col	The column in inflator_table by which times are mapped.
roll	If NULL, inflation is calculated only on exact matches in inflator_table. Otherwise, uses a rolling join. See data.table::data.table.
max.length	(Internal use only). If not NULL, the maximum length of x, from, and to known in advance. May be provided to improve the performance if known.

Value

A vector of inflated values. For example, inflator_table = grattan:::cpi_seasonal_adjustment, index.col = "obsValue", time.col = "obsTime", gives the CPI inflator.
