I think you want something like this:
df <- data.frame(cbind(1:10, 11:20))
names(df) <- c("y","x")
par(mar = c(7, 10, 7, 7))
plot(y ~ x, data = df, ylab = "", xlab = "independent")
text(par("usr")[1] - 1, 5.5, adj = 1, labels = "dependent", xpd = TRUE)

See the between argument. For example:
library(lattice)
df2 <- data.frame(Y = runif(20), X = rnorm(20), G =
rep(c("A","B","C","D"), each=5))
xyplot(Y ~ X | G, data = df2, layout=c(2,2), between=list(x=1,y=1))
