How to plot near zero values with qgraph?

问题

How can I plot very small/near zero values with the qgraph-package in R?

m <- matrix( data = c( 1, 0.5, 0.1, 0.01 ), ncol = 2 )

library( qgraph )
qgraph( input = m )

Experiment with the cut parameter. Your small values are likely present, they are just hard to see. Specifying cut adjusts the saturation width such that everything above the cut point have the strongest color intensity and everything below gets weaker the further it is from the cut point. By making this close to 0, the near 0 values will be plotted with more saturated colors than they would have been otherwise.

qgraph(input=m,cut=0.05)
