Add breakpoints to certain dates in a data set.

Usage

add_breakpoints(data, dates = as.Date(character(0)))

data: A <data.frame> of disease reports (confirm) by date (date). confirm must be numeric and date must be in date format. Optionally, data can also have a logical accumulate column which indicates whether data should be added to the next data point. This is useful when modelling e.g. weekly incidence data. See also the fill_missing() function which helps add the accumulate column with the desired properties when dealing with non-daily data. If any accumulation is done this happens after truncation as specified by the truncation argument. If all entries of confirm are missing (NA) the returned estimates will represent the prior distributions.
dates: A vector of dates to use as breakpoints.

A data.table with breakpoint set to 1 on each of the specified dates.

reported_cases <- add_breakpoints(example_confirmed, as.Date("2020-03-26"))
