DiscountFactor class

Source: R/interest-rate-classes.R

The DiscountFactor class is designed to represent discount factors. Checks whether: d1 is less than d2, elementwise, and that both are Date vectors; and value is greater than zero and is a numeric vector. An error is thrown if any of these are not true. The elements of each argument are recycled such that each resulting vectors have equivalent lengths.

DiscountFactor(value, d1, d2)

Arguments

value

a numeric vector containing discount factor values. Must be greater than zero
d1

a Date vector containing the as of date
d2

a Date vector containing the date to which the discount factor applies

Value

a (vectorised) DiscountFactor object

Examples

library("lubridate")
df <- DiscountFactor(c(0.95, 0.94, 0.93), ymd(20130101), ymd(20140101, 20150101))
as_InterestRate(df, 2, "act/365")
#> <InterestRate> 5.195670%, SEMI-ANNUAL, ACT/365
#> <InterestRate> 3.117823%, SEMI-ANNUAL, ACT/365
#> <InterestRate> 7.390339%, SEMI-ANNUAL, ACT/365
