v0.2.1

New Functionality

• Can keep leading zeros when using fashion() with new argument leading_zeros = TRUE.
• New optional arguments added to plotting functions, network_plot() and rplot():
  • legend to display a legend mapping correlations to size and colour.
  • colours (or colors) to change colours in plot.

Fixes

• network_plot() no longer plots wrong colours if only positive correlations are included.
• Colour scheme for network_plot() changed to match rplot().
• Other bug fixes.
