Creates an overlay plot for class 'data.frame'. Continuous items are plotted vs last continuous item in names(x), conditioned (facetted) by up to two categorical items.
# S3 method for data.frame
overlay(x, ncol = 4, nrow = 4, color = "black",
points = TRUE, line = "solid", ylab = NULL, xlab = NULL,
ylog = FALSE, xlog = FALSE, ...)folded. See fold.
