add_breakpoints function

Add breakpoints to certain dates in a data set.

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

Arguments

• data: A <data.frame> of disease reports (confirm) by date (date). confirm must be numeric and date must be in date format. Optionally this 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.
• dates: A vector of dates to use as breakpoints.

Returns

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

Examples

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