Description Usage Arguments Author(s) References See Also Examples
Uses a scatterplot to display the relationship of a set of returns to a market benchmark. Fits a linear model and overlays the resulting model. Also overlays a Loess line for comparison.

|
Ra |
a vector of returns to test, e.g., the asset to be examined |
Rb |
a matrix, data.frame, or timeSeries of benchmark(s) to test the asset against |
Rf |
risk free rate, in same period as the returns |
excess.returns |
logical; should excess returns be used? |
reference.grid |
if true, draws a grid aligned with the points on the x and y axes |
main |
set the chart title, same as in |
ylab |
set the y-axis title, same as in |
xlab |
set the x-axis title, same as in |
xlim |
set the x-axis limit, same as in |
colorset |
color palette to use |
symbolset |
symbols to use, see also 'pch' in |
element.color |
provides the color for drawing chart elements, such as the box lines, axis lines, etc. Default is "darkgray" |
legend.loc |
places a legend into one of nine locations on the chart: bottomright, bottom, bottomleft, left, topleft, top, topright, right, or center. |
ylog |
Not used |
fit |
for values of "loess", "linear", or "conditional", plots a line to fit the data. Conditional lines are drawn separately for positive and negative benchmark returns. "Quadratic" is not yet implemented. |
span |
passed to loess line fit, as in |
degree |
passed to loess line fit, as in |
family |
passed to loess line fit, as in |
ylim |
set the y-axis limit, same as in |
evaluation |
passed to loess line fit, as in |
legend.cex |
set the legend size |
cex |
set the cex size, same as in |
lwd |
set the line width for fits, same as in |
... |
any other passthru parameters to |
