ans <- optimx(fn = function(x) sum(x*x), par = 1:2) # order by method name. summary(ans, order = rownames) # order by objective value. Do not show parameter values. summary(ans, order = value, par.select = FALSE) # order by objective value and then number of function evaluations # such that objectives that are the same to 3 decimals are # considered the same. Show only first parameter. summary(ans, order = list(round(value, 3), fevals), par.select = 1)
