Hi, Does anybody have a hint why this does not work?
plot(c(1991,2000), c(-1,10))abline(a=6, b=-1, col="dark grey", lty="dashed") It does not generate an error message, but the line does not turn up. If b=0 it works fine. If I change the axes of the plot to plot(c(1,10), c(-1,10)) it does work fine as well.
