I have this graphics using R. The final line is:
> dca(data=data.set, outcome= "Result", predictor="phat_corrected", xstop=0.9)
Is there a color area in dca comment?
On the other hand, I can draw only one model at a time with this command.
I see 3-4 models in one net benefit graphic at once in some articles, and it is a good way to compare them. How do authors plot multiple models' result at once with different color? I've sent this question but I had no return.
Please help. Do I need to use a command other than dca? Can I give color to the curve after I've got them by using dca command?
Dear Mutlu Gulbay
You should be able to specify colors and line-types using the following code:
dca(data= ...)
lines(dcaoutput$X, model1, type="l", col=1, lty=2)
lines(dcaoutput$X, model2, ...)
Using that syntax, you should be able to add more models to the figure.
If you'd like to try something slightly different, I would suggest following this tutorial: https://www.danieldsjoberg.com/dca-tutorial/dca-tutorial-r.html
Best wishes,
Francesco
