Pad values on the left side of input

leftpad_input(input, new_offset, padding_value = 0)

Arguments

input

Module input object. List with two elements:

  1. A numeric vector named values: the incidence recorded on consecutive time steps.

  2. 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.

new_offset

Offset of output.

padding_value

Value to left-pad input with.
