[R] abline limit constrain x-range how?

[Giovanni Azua]

Hello,

I managed to "linearize" my LDA decision boundaries now I would like to call abline three times but be able to specify the exact x range. I was reading the doc but it doesn't seem to support this use-case? are there alternatives. The reason why I use abline is because I first call plot to plot all the three datasets and then call abline to "append" these decision boundary lines to the existing plot ...

Can anyone please advice?
Thanks in advance,
Best regards,
Giovanni
