list whose components are numeric vectors of the x values for overlaid curves
yList
list whose components are numeric vectors of the y values for overlaid curves
tList
list of character string texts to insert in plot
sortB
Boolean if TRUE staggered curves reordered, with
largest range curve on bottom of graph
verbose
Boolean if TRUE print informative or diagnostic messages to console
Details
In order to unclutter the overlay plot, we need to stagger the graphs
the offset for each graph will be the sum of the max values for all
of the preceding graphs.
So the stack of staggered graphs will have max y (ie, ymax) equal to
the sum of the max's.
# demonstrate effect of sorting the curves
plot.new()
stagger(xList2,yList2,textList,sortB=FALSE,verbose=TRUE)
stagger(xList2,yList2,textList,sortB=TRUE,verbose=TRUE)
