Function to plot a dendrogram based on gene interaction — plot_network

This function takes an adjacency matrix representing a gene regulatory network and builds a dendrogram based on the stength of gene interactions

plot_network_dendrogram(adj_mat, dist_method = "euclidean")

Arguments

adj_mat	an adjacency matrix to plot the dendrogram from.
dist_method	method to be used to calculate distances Default is `euclidean`.

Examples

# path to PPCOR output file
ppcor_output <- system.file('beeline_examples/PPCOR/outFile.txt', package = 'edgynode')
# import PPCOR specific output
ppcor_parsed <- ppcor(ppcor_output)
# rescale matrix
ppcor_rescaled <- network_rescale(ppcor_parsed)
#> It seems like your input matrix contains values of correlation coefficients range(-1,1). Please be aware that for negative values the absolute value will be taken before rescaling. We transformed all negative values to their absolute values.
# plot dendrogram
plot_network_dendrogram(ppcor_rescaled)
