Hi all,

I'm currently loving the PCATools package, it is very neat and easily replaces my own comparatively crude efforts using ggplot2()

When producing a pairsplot() I was wondering if it was possible to output a single legend (top, bottom, right or left) to be used as a reference for all the individual biplots? Currently when using legendPosition = 'bottom' (for example), each biplot has its own legend, which is a bit redundant and also squishes all the biplots.

Many thanks.

For this, you'll have to plot each as a panel via cowplot::plot_grid() and make use of the rel_widths parameter. Or, it may even be easier to output each with the legend and do some post-editing outside of R.
