x |
a fitted range shift object, i.e. output of the |
bars |
whether or not to draw "bars" - i.e. estimates of the range shift corridor (these are often poorly rendered and are a work in process) |
bar.params |
a vector of 3 simulation values, useful for smoothing the bars in the dumbbell plot. For smoothing, it might be recommended to increase the first value, |
plot.ts |
whether or not to plot the time series as well |
stretch |
an extra parameter to extend the bars on the dumbbells (in real distance units). |
pt.cex |
point character expansion. |
pt.col |
points color. |
CI.cols |
three shading colors, from lightest to darkest. The default is a sequence of blues. |
layout |
the default layout places the x-y plot on the left and - if |
par |
graphics window parameters that, by default, look nice with the default layout. |
... |
additional parameters to pass to plot function (e.g. labels, title, etc.) |

# it is helpful to have some initital values for these parameters
# because the automated quickfit() method is unreliable for three ranges
# in the example, we set a seed that seems to work
