Net Present Value of a periodic cashflow (NPV)

Net Present Value of a periodic cashflow (NPV)

npv(i, cf, ts = seq(from = 0, by = 1, along.with = cf))

`i`	The rate used to discount the cashflow. It must be effective and with a periodicity that matches that of the cashflow
`cf`	The cashflow
`ts`	The times on which the cashflow ocurrs. It is assumed that `cf[idx]` happens at moment `ts[idx]`. If empty, assumes that `cf[idx]` happens at period `idx - 1`

The net present value at

npv(i = 0.01, cf = c(-1, 0.5, 0.9), ts = c(0, 1, 3))
