questions about *, ** and ***

[justoneee]

The correlation diagram I drew with sjp.corr is very nice and the code is very minimalist, however I would like to ask what the *, ** and *** in the diagram mean respectively, I didn't find an explanation inside the help file. Also what can I use to add comments under the sjp.corr results?

Could be better explained in the docs. It's the different significance levels (p < 0.05, p<0.01, p<0.001).
