logarithmically scaled y-axis in vioplot

Dear all

I am trying to make a graphic with the "vioplot" package. I use the following code:

library(vioplot)
x1<- GSMrxDL
x2<- WIFI
x3<- UMT
vioplot(x1, x2, x3, ylim=c(0, 10), names=c("GSMrxDL", "WIFI", "UMT"), col="gold")
title("NIS Strahlung", xlab="Sender", ylab="V/m")

Now I want to scale the y-axis logarithmically, i.e. 0.01; 0.1; 1; 10. How can I do this?

Thank you very much

Alex
