Another option is using page, as in this example from ?splom:

splom(~iris[1:3]|Species, data = iris,
      layout=c(2,2), pscales = 0,
      varnames = c("Sepal\nLength", "Sepal\nWidth", "Petal\nLength"),
      page = function(...) {
          ltext(x = seq(.6, .8, len = 4),
                y = seq(.9, .6, len = 4),
                lab = c("Three", "Varieties", "of", "Iris"),
                cex = 2)
      })
