Extracts a Single Column, Summarises if from Simulation

model_df_to_vector(df, com_var, id_var = NULL, sum_fn = NULL)

Arguments

df	A data frame of dynamic system output.
com_var	The vector to be compared; use unquoted name (NSE).
id_var	A character string indicating the id variable to summarise over if required.
sum_fn	The summary function to be used, defaults to median.

Value

Returns a numeric vector, summarised if required.
