R code for visualization of similarity matrices, by reordering them so high values move to the diagonal (become "slanted"), and optionally apply order-preserving clustering to the result.
View slant.r
#' Compute rows and columns orders which move high values close to the diagonal.
#' For a matrix expressing the cross-similarity between two (possibly different)
#' sets of entities, this produces better results than clustering (e.g. as done
#' by \code{pheatmap}). This is because clustering does not care about the order
#' of each two sub-partitions. That is, clustering is as happy with \code{((2, 1),
#' (4, 3))} as it is with the more sensible \code{((1, 2), (3, 4))}. As a result,
#' visualizations of similarities using naive clustering can be misleading.
#' @param data A rectangular matrix.
