[R] y-axis log scale in library lattice

[Duarte Viana]

Hello all,

Is there an argument in function "xyplot"  (library "lattice")
equivalent to log="y" in base graphics?
I mean transforming the axis, not the variable, as the help on
argument log in"scales" says "Note that this is a transformation of
the data, not the axes".

Thanks in advance,

Duarte Viana
