This function ensures that an incidence object has the same range of dates
for each grouping. By default missing counts will be filled with 0L
.
Arguments
- x
<incidence2>
object.- expand
logical
.Should a range of dates from the minimum to maximum value of the date index also be created.
If
expand
is TRUE (default) then complete_dates will attempt to usefunction(x) seq(min(x), max(x), by = 1)
to generate a complete sequence of dates.- fill
numeric
.The value to replace missing counts by.
Defaults to
0L
.- by
Defunct
.Ignored.
- allow_POSIXct
logical
.Should this function work with POSIXct dates?
Defaults to
FALSE
.
Value
An incidence2 object.
Examples
x <- data.frame(
dates = Sys.Date() + c(1,3,4),
groups = c("grp1","grp2", "grp1"),
counts = 1:3
)
i <- incidence(x, date_index = "dates", groups = "groups", counts = "counts")
complete_dates(i)
