# rCumSum: Plot cummulative returns In realized: Realized

## Description

Plots cummulative returns at a certain alignment given a return series.

## Usage

 `1` ```rCumSum(x, period = 1, align.by="seconds",align.period = 1, plotit = FALSE, type = "l", cts = TRUE, makeReturns = FALSE) ```

## Arguments

 `x` Tick data in xts object. `period` Sampling period `align.by` Align the tick data to seconds|minutes|hours `align.period` Align the returns to this period first `plotit` T for plot `type` Line or points `cts` Create calendar time sampling if a non realizedObject is passed `makeReturns` Prices are passed make them into log returns

## Value

Cummulative return vector if plotit = F
