  "month", "daily"))

Arguments

G

numeric vector that contains the gradient value(s)

n

numeric vector that contains the period value(s)

i

numeric vector that contains the interest rate(s) as a percent

frequency

character vector that contains the frequency used to obtain the number of periods [annual (1), semiannual (2), quarter (4), bimonth (6), month (12), daily (365)]

Value

• AgivenG numeric vector that contains the annual value(s) rounded to 2 decimal places

encoding

UTF-8

Details
