Calculate embodied energy matrices

Source: R/embodied.R
calc_M.Rd

M is calculated by e_hat * G, but e_hat contains lists of matrices, so the M is also contain lists of matrices. In each list, there is one M matrix for each Product in the Energy conversion chain.

Usage

calc_M(
  .YqGHEdata = NULL,
  Y = "Y",
  q = "q",
  G = "G",
  E = "E",
  tol = 1e-04,
  M_p = "M_p",
  M_s = "M_s"
)

Arguments

.YqGHEdata

A data frame containing columns of q vectors and Y, G, H, and E matrices. .YqGEdata will likely have been obtained from the calc_GH() and calc_E() functions.

Y

A final demand (Y) matrix or name of the column in .YqHGEdata containing same. Default is "Y".

q

A q column vector or name of the column in .YqHGEdata containing same. Default is "q".

G

A G matrix or name of the column in .YqHGEdata containing same. Default is "G".

E

An E matrix or name of the column in .YqHGEdata containing same. Default is "E".

tol

The allowable energy balance error.

M_p

The name for matrices of embodied energy in products on output. Default is "M_p". These matrices contain embodied products in rows and embodying products in columns.

M_s

The name for matrices of embodied energy consumed by final demand sectors. Default is "M_s". These matrices contain embodied products in rows and consuming final demand sectors in columns.

Value

A list or data frame of embodied energy matrices.
