May I suggest an alternative, possibly easier than using lattice:
x <- log(seq(1,11,1))
y <- seq(0,1,0.1)
# set the margins and 'xpd' allows to plot outside the range
par(mar=c(5,5,5,7), xpd=T)
# plot the data within the range
plot(x,y, type="l", col="blue", frame=F, xlim=c(0,2.5))
points(x[3],y[3], col="blue", pch=3, cex=2)
# add the outlier by specifying the coordinate x and/or y outside the range
points(2.9, 1, col='blue', pch=20, cex=2)
