num_dt: Compute median date, range.

Given a single integer vector (with origin specified) or data class vector, will compute median day and a range (default min/max) and percent of total, returning results in string. Mostly called by other functions.

num_dt(x, median = TRUE, range='min/max', origin=NULL)

Arguments

range	A character string to indicate range values. options: 'min/max'.
origin	Default NULL. If specified, must be a date class object of length 1. For use if date variable is in raw integer format.
x	A integer or date class vector
nomedian	A logical vector, indicates whether to report median or not. Default = TRUE.

Value

A character string of length 1, 'Median date (date1, date2)'
