Generate dummy variable name from set name

Creates a short dummy variable name from a set name following conventions:

• Uses preferred names for common sets (tech -> h, timeslice -> ts, etc.)

• First letter of the set name (lowercase) for others

• Two letters for an alias (checked against all_set_names)

• Ensures uniqueness by checking against all symbols in model

Usage

generate_index_alias(
  set_name,
  used_names = character(0),
  all_set_names = character(0),
  all_symbols = NULL
)

Arguments

set_name

Character. The name of the set

used_names

Character vector. Names already used (to avoid conflicts)

all_set_names

Character vector. All set names in the model (to detect aliases)

all_symbols

List. All symbols in model (sets, parameters, variables, etc.) to avoid conflicts

Value

Character. A short dummy variable name

Examples

generate_index_alias("tech") # "h"
#> [1] "h"
generate_index_alias("timeslice") # "ts"
#> [1] "ts"
generate_index_alias("commp", all_set_names = c("comm", "commp")) # "cp"
#> [1] "cp"
