Dear forum,
I need to create biplot graphic. I took a look at the code of the
biplot.default function from the stats package and I found that the arrows for
the variables are multiplied by a coefficient of 0.8 before plotting:
...
if (var.axes)
arrows(0, 0, y[, 1L] * 0.8, y[, 2L] *
Probably so that the end of the arrow does not overplot the labels.
