DescriptionFor a general two parameter density, draws a contour graph where the contour lines are drawn at 10 percent, 1 percent, and .1 percent of the height at the mode.
Usagemycontour(logf,limits,data,...)Arguments
logf | function that defines the logarithm of the density |
limits | limits (xlo, xhi, ylo, yhi) where the graph is to be drawn |
data | vector or list of parameters associated with the function logpost |
... | further arguments to pass to contour |
