leftpad_input(input, new_offset, padding_value = 0)
| input | Module input object. List with two elements: 
 | 
|---|---|
| new_offset | Offset of output. | 
| padding_value | Value to left-pad input with. | 
Module input object. List with two elements:
A numeric vector named values: the incidence recorded on consecutive time steps.
An integer named index_offset: the offset, counted in number of time steps,
by which the first value in values is shifted compared to a reference time step
This parameter allows one to keep track of the date of the first value in values
without needing to carry a date column around.
A positive offset means values are delayed in the future compared to the reference values.
A negative offset means the opposite.
