Dear list, Please I need some assistance. I have been asked to produce a 1:1 line (dashed) and a line of best fit (solid) in a scatter plot. I have tried geom_abline() but it gives only the solid line. I also tried lty("dashed") to get the dashed line but it not working. I would be glad if I could get some assistance on how to do it.
Best regards, Enoch. [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
