Need a diagram of a Neural Network and don't feel like drawing 250 lines in PowerPoint/Inkscape? Use ggMLP()!
Depends on ggplot2 and dplyr.
Simply give as input a vector with the number of nodes per layer.
source("path/to/ggMLP/ggMLP.R")
# A fully connected neural network with 4 layers, each with
# 3, 7, 12 and 3 nodes respectively
nn = c(3, 7, 12, 3)
ggMLP(nn, linewd=.5, node_sep = 'compact')
