In cmu-delphi/epipredict: Basic epidemiology forecasting methods

Values for ahead and lag must be integer values

Code
  r1 <- epi_recipe(x) %>% step_epi_ahead(death_rate, ahead = 3.6) %>%
    step_epi_lag(death_rate, lag = 1.9)
Condition
  Error in `step_epi_lag()`:
  ! `lag` must be a non-negative integer.

A negative lag value should should throw an error

Code
  r2 <- epi_recipe(x) %>% step_epi_ahead(death_rate, ahead = 7) %>% step_epi_lag(
    death_rate, lag = -7)
Condition
  Error in `step_epi_lag()`:
  ! `lag` must be a non-negative integer.

A nonpositive ahead value should throw an error

Code
  r3 <- epi_recipe(x) %>% step_epi_ahead(death_rate, ahead = -7) %>% step_epi_lag(
    death_rate, lag = 7)

Values for ahead and lag cannot be duplicates

Code
  slm_fit(r4)
Condition
  Error in `add_shifted_columns()`:
  ! Name collision occured in <step_epi_lag>
  The following variable name already exists: "lag_7_death_rate".
