diff_basis: differences of periodic cumsums

In vh-d/VHtools: help functions for daily usage

Description

Compute diffences of values that are cumulative sums restarting from 0 every period such as accouting values.

Usage

diff_basis(x, t, tbase = 1, ...)

Arguments

x	numeric/integer vector
t	time index
tbase	value of time index where cumulative sums starts from 0
...	args passed to 'diff_fill()'

Value

return

Examples

ts <- c(cumsum(rnorm(12, 3)), cumsum(rnorm(12, 5)))
plot(ts, type = "l")
plot(diff(ts), type = "l")

tsd <- diff_basis(ts, rep(1:12, times = 2))
plot(tsd, type = "l")
