overriding axis labels after plot in R -- not working if plotting an scb object?

What should I check about the object I plot to be able to override the axis labels, which remain variable names generated be the scb call instead of my specification below? scb is in the locfit library: http://cran.r-project.org/web/packages/locfit/locfit.pdf

fit2<-scb(closed_rule ~ lp(bl),deg=1,xlim=c(0,1),ev=lfgrid(100), family='binomial',alpha=cbind(0,0.3),kern="parm")
pdf('figure1.pdf')
plot(fit2,ylab = "Predicted closed rule probability", xlab="Lobbyist bias", xlim=c(0,1), ylim=c(0,1))
dev.off()

I found no relevant object of fit2 to override -- and I am not even sure why this should be necessary if I specify labels myself. I see one called varnames, that has a single element corresponding to the future x-axis label, but overriding it does not help my labels show, and the ylabel is definitely coming from some completely other place anyway.

The axis labels are kind of predefine in the plot.scb function.

If you type > plot.scb you will see that either plot.scb.1d or plot.scb.2d are used.

plot.scb.1d use the content of fit2$vnames[1] for the x axis. To change the ylab value you will have to hack the function by replacing the plot line in plot.scb.1d by something like that:

...
plot(x$xev, fit, type = "l", ylim = yl, ylab = "Predicted closed rule probability", xlab="Lobbyist bias")
...

For plot.scb.2d it is easier xlab=fit2$vnames[1] and ylab=fit2$vnames[2]. Here, I would change the value(s) of fit2$vnames.
