intervals: intervals

In benwhicks/lakit: Learning Analytics Kit

Description

Function that takes a numeric vector and outputs the difference between each succsessive member. It also needs to know where to place a 0 - either at the end of the vector (matching each difference with where it left from) or at the beginning of the vector (matching each difference with where it goes to).

Usage

intervals(x, end_at_0 = TRUE, sub_0 = 0)

Arguments

x	a numeric vector (can be dates, etc)
end_at_0	decision on where to place the 0 to return vector of the same length. Defaults to TRUE, indicating the output matches with where the element is leaving from.
sub_0	What this places for the end_at_0 parameter. Defaults to 0

Examples

v <- c(1,2,3)
intervals(v)
intervals(v, FALSE)
intervals(v, TRUE, NA)
