Need to produce an error or convert if data.table object is provided as input
library(data.table)
library(incidence2)
dat <- incidence2::covidregionaldataUK
incidence(dat, date, count = cases_new)
#> An incidence object: 490 x 2
#> date range: [2020-01-30] to [2021-06-02]
#> cases_new: 8379330

#> date_index cases_new
#> <date> <dbl>

setDT(dat)

#> Error in `[.data.table`(x, date_index): When i is a data.table (or character vector), the columns to join by must be specified using 'on=' argument (see ?data.table), by keying x (i.e. sorted, and, marked as sorted, see ?setkey), or by sharing column names between x and i (i.e., a natural join). Keyed joins might have further speed benefits on very large data due to x being sorted in RAM.Created on 2021-08-23 by the reprex package (v2.0.1)
