pad timesteps from BirdFlow models — pad

This function is mostly for internal use but exported for advanced users. It's primary purpose is to pad timesteps with zeros for looking up transition names. It is called from lookup_transitions() which is in turn used by get_transition(). Padding is generally two digit but the level of padding is stored in the BirdFlow object so that we'll be able to switch to three digit timesteps easily if, for example, someday we decide to have daily timesteps.

Usage

pad_timestep(x, bf)

Arguments

x: A vector of timestep integers
bf: A BirdFlow model

Value

a string with padded versions of x; 1 becomes "01".

Examples

bf <- BirdFlowModels::amewoo
pad_timestep(1:5, bf)
#> [1] "01" "02" "03" "04" "05"
