Write the legend in a DAG drawing.
Lists the DAG symbols along with their names/labels below a DAG drawn.
dag.legend(dag, lx = -0.15, ly = -0.075, alt.symb = TRUE)
dag |
The DAG for which the legend is needed. |
lx |
X coordinate for repositioning legend. |
ly |
Y coordinate for repositioning legend. |
alt.symb |
Boolean indicating if the alternative node symbols (dag$symbols) should be used. Note that the formatting is not changed, i.e. longer symbols will not be formatted nicely. |
