plotTertiles: Plot elicted tertiles, median and plausible range for each expert
Description
Displays a horizontal bar for each expert, to represent the expert's plausible range.
The coloured sections indicate the experts' tertiles: three intervals judged by the expert
to be equally likely. The experts' medians are shown as dashed lines.
a matrix of elicited tertiles and medians: one column per expert, first
row is the 33rd percentile, 2nd row is the median, last row is the 66th percentile.
lower
a vector of lower plausible limits: one per expert
upper
a vector of upper plausible limits: one per expert
