Use processDocument() to split handwritting into component shapes called
graphs. plot_graphs() creates a plot that displays the graphs. ggplot2::facet_wrap()
places each graph in its own facet, and ncol sets the number of columns of facets.
Usage
plot_graphs(doc, ncol = NULL)
Value
A plot of all graphs in the document
Arguments
doc
A PNG image of handwriting processed with processDocument().
ncol
Optionally, set the number of columns in the output plot. The default is NULL
which allows ggplot2::facet_wrap() to automatically choose the number of columns.
