Description

Generates parameter initialization code based on a parameter table, handling both fixed and estimated parameters.

Usage

initialize_param(param_name, param_table)

Value

Character vector containing generated initialization code line. Format:

• Fixed parameters: <param_name> <- fix(initial_value)

• Estimated parameters: l<param_name> <- initial_value

Arguments

param_name

Character, name of the parameter to initialize (without "l" prefix)

param_table

Dataframe containing parameter specifications, must include:

• Name: Character parameter names with "l" prefix (e.g., "lka" corresponds to param_name="ka")

• init: Numeric initial values

• fixed: Integer flag (0/1) indicating fixed status (1 = fixed)

Examples

# Create sample parameter table
param_table <- initialize_param_table()

# Generate initialization code
initialize_param("ka", param_table)  # Returns "ka <- fix(0.500)"
initialize_param("cl", param_table)  # Returns "lcl <- 1.200"
