Description Usage Arguments Value Author(s) References See Also Examples

Converts a proportion gain over one or several years to an average daily gain. For example, an investment that gains 15% over 3 years has an average daily gain of approximately 0.0186%. The formula is: daily.gain = (total.gain + 1) ^ (1 / (252 * years)) - 1. Here total.gain and daily.gain are proportions, e.g. 0.15 for 15%.

1	yearly.daily(total.gain, years = 1)

`total.gain`	Numeric value (or vector) representing the proportion gain of an investment over the number of years specified.
`years`	Number of years.

Numeric value indicating average daily gain.

yearly.daily(total.gain = 0.15, years = 3)

# Figure out daily gain required for various gains over a 5-year period
yearly.daily(total.gain = seq(0, 2, 0.25), years = 5)
