Find lowest-cost way to assemble units of different sizes to a certain total

1 2	find_least_cost_partition(desired_dose, available_units, subset_col = NULL, subset_val = NULL)

`desired_dose`	the dose(s) required.
`available_units`	available sizes and costs; must have column names 'size' and 'cost'
`subset_col`	optionally, a column to select on.
`subset_val`	if subset_col is provided, the value to select on in that column.

a data frame, with columns desired_dose, used_dose, waste, cost, and cost.no.waste

units <- data.frame(size = c(1000, 250, 200, 100, 50),
    cost = c(40, 11.5, 8.5, 5.5, 4.4))
find_least_cost_partition(450, available_units = units)
temp <- find_least_cost_partition(sample(250:450, 10, replace = TRUE), 
   available_units = units)
