I'd like to have a function to draw correct grid while using log axis with

h - latticeExtra:::logTicks(2^lim$ylim,

You have your data in a wide format, but you want it in a long format.

This was however for plotting. For subset regression by each WR without

I'm not sure what you are trying to achieve, but I think this can be a good
starting point:
