simplify_edge_list: Simplify an edge list

In MatthewHeun/Recca: R Energy Conversion Chain Analysis

Simplify an edge list

Description

A PSUT energy conversion chain edge can be simplified if a product has only one supplier (i.e., one "from"). Then, every "to" node for that product can have the product's "from" be its "from". See examples.

Usage

simplify_edge_list(
  edge_list,
  from = "From",
  to = "To",
  value = "Value",
  product = "Product"
)

Arguments

edge_list	the edge list to be simplified
from	the name of the from column in the edge list. (Default is "From".)
to	the name of the to column in the edge list. (Default is "To".)
value	the name of the value column in the edge list. (Default is "Value".)
product	the name of the product column in the edge list. (Default is "Product".)

Value

a simplified edge list

Examples

el <- data.frame(From = c("A", "Oil"), To = c("Oil", "C"),
                 Value = c(42, 42), Product = c("Oil", "Oil"),
                 stringsAsFactors = FALSE)
# Oil flows from A to C through its product node (Oil)
el
# Simplify to have Oil flow from A to C without the product node
simplify_edge_list(el)
