Have you looked at the last example in ?layout, which has a scatterplot
with marginal histograms for the x and y axes?

Alternatively, you can generally reverse the x and y values for most
plots. For example, compare:

 d <- density(rnorm(100))

 # Vertical density plot
 plot(d)

 # Horizontal density plot 
 plot(d$y, d$x, type = "l", xlab = "Density", 
      main = "density(y = rnorm(100))",
      ylab = paste("N =", d$n, "  Bandwidth =", formatC(d$bw)))
