I still don't see the problem. When I do > x <- 1:100 > y <- (1:100)/10 > plot(xy.coords(x, y, log="xy")) I don't see a log scale being used. To get that, I'd need plot(xy.coords(x, y, log="xy"), log="xy") and in this case, I can't see how you could tell what base is being used: the tick marks are labelled in the original scale.
