Create a strategy target vector

ledgr_target() creates a thin wrapper around the full named numeric target quantity vector consumed by ledgr's existing strategy-result validator. A zero-length target is valid when no non-empty universe is supplied; a supplied non-empty universe still requires one target per instrument.

Usage

ledgr_target(x, universe = NULL, origin = NULL)

Arguments

x

Full named numeric target-quantity vector.

universe

Optional universe. When supplied, names must exactly match it.

origin

Optional helper/source label for printing.

Value

A ledgr_target object.

Examples

target <- ledgr_target(c(AAA = 1, BBB = 0), universe = c("AAA", "BBB"))
target[["AAA"]]
#> [1] 1
c(target)
#> AAA BBB 
#>   1   0
