breaks_to_interval() takes a specified set of breaks representing the left
hand limits of a closed open interval, i.e [x, y), and returns the
corresponding interval and upper bounds. The resulting intervals span from
the minimum break through to a specified max_upper.
Arguments
- breaks
[integerish].1 or more non-negative cut points in increasing (strictly) order.
These correspond to the left hand side of the desired intervals (e.g. the closed side of [x, y).
Double values are coerced to integer prior to categorisation.
- max_upper
[numeric]Represents the maximum upper bound splitting the data.
Defaults to
Inf.
Value
A data frame with an ordered factor column (interval), as well as columns
corresponding to the explicit bounds (lower_bound and upper_bound). Note
these bounds are returned as <numeric> to allow the maximum upper bound to
be Inf.
Examples
brks <- c(0L, 1L, 5L, 15L, 25L, 45L, 65L)

#> 5 [25, 45) 25 45
#> 6 [45, 65) 45 65
