For axis(4). If you really want right justify on the right hand side,
you could use axis(2) with negative line numbers (device size
dependent). Or you could try something like
plot(1:20)
axis(2,at=seq(1,20,4),labels=T,tick=F,las=T,pos=c(22.25,1))
Hope this is getting there (after only 6 messages...)
