Reconstruct intlen from time variable and stored cut points

Source: R/make-newdata.R

Computes interval lengths from the sorted unique values of the time variable in newdata. This is used by add_* functions that need intlen for cumulative calculations. If tstart is not available, the first interval length is taken as the first sorted time value (implicitly assuming a 0-origin time scale).

reconstruct_intlen(newdata, time_var = "tend", interval_length = "intlen")

Arguments

newdata

A data frame with a time column (default tend).

time_var

Character name of the time variable. Defaults to "tend".

interval_length

Character name of the interval-length column to create.

Value

The input data frame with an intlen column added.
