I need to add legend in a consort plot generate by the {consort} package, but I can’t.

I tried inserting with the text function:

plot(fluxo)
text(1, 1, "text")

Error in text.default(0, 0, "text") : plot.new has not been called yet

So:

plot(fluxo)
plot.new()

Error in plot.new() : figure margins too large

Is there solution?
