[R] Ordering scales in xYplot.Hmisc

Dear R community,
I am using xYplot() from the Hmisc package. The package works great to
plot means + CI. But I am having issues handling the scales.
I am plotting "Soil Clay content" vs "Soil depth" by "land use".
Usually in this type of graphs it is better to place the variable "soil
depth" in the y-axis and it should be ordered downward by depth (0-5 cm,
5-10 cm, 10-20 cm).
I can't figure out how to sort/order the scale to obtain the graph I
need, any insights will be appreciated.
Best regards and have a nice weekend,
Jose
