RVenn (version 1.1.0)

setmap: Draw a clustered heatmap showing presence/absence of the elements.

Description

This function is based on the package 'pheatmap'. ggvenn function is useful for 2-3 sets, if you need to show interactions between many sets, you can show the presence/absence of the elements among all the sets and cluster both the sets and the elements based on Jaccard distances.

Usage

# S4 method for Venn
setmap(venn, slice = "all", element_clustering = TRUE,
  set_clustering = TRUE, method = "average", legend = TRUE,
  title = NA, element_fontsize = 10, set_fontsize = 10)

Arguments

venn

(Required) A Venn object.

slice

(Optional) The names or the indices of sets of interest. Default is "all", meaning the union will be calculated for all the sets.

element_clustering

(Optional) Boolean values determining if elements should be clustered.

set_clustering

(Optional) Boolean values determining if sets should be clustered.

method

(Optional) Clustering method used. Accepts the same values as hclust.

legend

(Optional) Boolean values determining if the legend should be drawn.

title

(Optional) Title of the heatmap.

element_fontsize

(Optional) Font size of the elements.

set_fontsize

(Optional) Font size of the sets.

Value

Presence/absence heatmap of the sets.

Examples

# NOT RUN {
venn = Venn(list(letters[1:10], letters[3:12], letters[6:15], letters[9:16],
letters[15:25], letters[12:20]))
setmap(venn)
setmap(venn, slice = 1:4, element_clustering = FALSE, set_clustering = FALSE)
# }
