unitconv: Calculate unit conversion factors

In JGCRI/iamrpt: Convert GCAM results to the format required by various IAM experiment databases

Description

Return a factor for converting the input unit to the output unit. This factor should be applied as a multiplier: out = in * fac. In the event the conversion could not be performed (e.g., because one of the units couldn't be identified), NA will be returned (we return NA instead of NULL so that you can multiply several conversion factors and check once at the end whether they all succeeded).

Usage

unitconv_counts(iunit, ounit, inverse = FALSE)

unitconv_energy(iunit, ounit, inverse = FALSE)

unitconv_usdollar(iunit, ounit, inverse = FALSE)

Arguments

iunit	Units for the input data
ounit	Desired output unit.
inverse	If TRUE invert the conversion factor. Use this in cases where the unit being converted is in the denominator; e.g. cost/EJ -> cost/MWh.

Functions

• unitconv_counts: Convert counting units (thousands, millions, etc.)

  Supported units are described in parsecounts.

• unitconv_energy: Convert energy units

  Supported units: EJ, TJ, MJ, MWh

• unitconv_usdollar: Adjust US Dollar units for inflation.

  Convert US dollar units from one dollar year to another using the GDP deflator obtained from the Federal Reserve's FRED database.
