Is this object a tbl_nowcast?

Tests whether an object is a fitted nowcast – the thing run_nowcast() returns – rather than the data a nowcast is fitted to (for which see is_tbl_now()).

Usage

is_tbl_nowcast(x)

Arguments

x

An object.

Value

A single TRUE when x is a tbl_nowcast, FALSE otherwise.

See also

tbl_nowcast for the class itself; run_nowcast() which produces one; is_tbl_now() for the input side.

Examples

# A number is not a nowcast.
is_tbl_nowcast(1)
#> [1] FALSE

## The object run_nowcast() returns is.
predictions <- data.frame(
  onset_week = as.Date("2020-01-05"),
  .quantile_level = c(0.5, 0.9), .value = c(10, 14)
)
nc <- tbl_nowcast(
  predictions = predictions, method = "toy", event_date = "onset_week"
)
is_tbl_nowcast(nc)
#> [1] TRUE
