A time series chart demonstrating drawdowns from peak equity attained through time, calculated from periodic returns.
chart.Drawdown(
R,
geometric = TRUE,
legend.loc = NULL,
colorset = (1:12),
plot.engine = "default",
...
)an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns

places a legend into one of nine locations on the chart: bottomright, bottom, bottomleft, left, topleft, top, topright, right, or center.
