This plots.

library(plotrix)  # should go here.

This throws an error even with plotrix loaded.

Try using the rgb function to create transparent colors:

[1] "#FF00004D"

The above _does_ plot with transparent color, but the below will not  
without data.

After a bunch of cutting and pasting of the yhyp1 data. I still get  
errors because y1upper and y1lower are not defined (nor their values  
implied by what you have written.)

Learn to use dput and review your code to see what variables are  
undefined.
