Ordering lattice bwplot

Question

I am plotting data by week using a lattice bwplot and am having trouble figuring out how it is deciding to sort the plots for each day. It showing (left to right, top to bottom): Tuesday, Wednesday, Friday, Monday, Thursday. Rather, I want it to show in the order of (left to right, top to bottom): Monday, Tuesday, Wednesday, Thursday, and Friday. Unfortunately I can't post an image to show the exact plot since I don't have a 10 reputation on SO.

Here are the first 6 rows of my data (the object is too big for dput). Imagine this repeating for 3,810 rows...

And, here is my function call for the bWplot:

bwplot(netKW~H_M|WkDay,data=DS1, scales=list(x=list(rot=45)), ylab='netKW', xlab=xlab, main=main)

I have looked into other posts about defining the lattice plot order and they seem to be leading to a common solution of changing the factor level order... In my case, it would be for WkDay. However, I am having trouble figuring out how to apply this to my specific problem.

 DS1$WkDay <- factor( DS1$WkDay, levels=c( 'Monday', 'Tuesday', 'Wednesday', 
                                           'Thursday', 'Friday') )

You should realize that lattice plots are from bottom to top, so expecting it to be from top to bottom is swimming against the stream so to speak. See the as.table argument on the ?bwplot help page for a mechanism to alter that default behavior.
