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