[R] xyplot lattice fine control of axes limits and thick marks (with log scale)

After a long and winding road (sorry but I'm a novice) I get to a final
result which is quite close to what I need; 
nevertheless I would like to tweak a little further the xyplot so that I can
get ***for each single panel defined by variable z*** a finer control over:
-the x and y the limits: I would like to be the same for both axes;
-the number of thick marks: again I would like to be same for both axes;

the (general) code snippet here attached does not get this result;
any help for this ?

thank you

#my example

xyplot(y ~ x | z, data=mydata,
       scales= list(x=list(relation="free", log=10),
                    y=list(relation="free", log=10)),
       prepanel = function(x, y, subscripts) {
         list(xlim = c(min(x,y), max(x,y)))
         list(ylim= c(min(x,y), max(x,y)))
       panel = function(x, y ,subscripts,...) {
         #panel.xyplot(x, y, xlim = c(min(x,y), max(x,y)), ylim =
c(min(x,y), max(x,y)),...)
         panel.xyplot(x, y, ...)
         panel.abline(a = 0, b = 1, lty = 2, col ="gray")
         panel.text(x, y, labels=mydata$name[subscripts])
       xscale.components = xscale.components.logpower,
       yscale.components = yscale.components.logpower
