Hi Jim, Thanks for the input but that did not work. I am suing Rstudio by the way and I guess that has a better device that would support ggplot output.
The annotate options works but that does not explain why the geom_area does not work: annotate("rect", xmin=2, xmax=10, ymin=0, ymax=1, fill="black", alpha=0.5) Best Adel -- Adel Daoud, PhD, Researcher The New School for Social Research, Visiting Scholar in the Economics Department, 6 East 16th Street New York, NY 10003, dao...@newschool.edu University of Gothenburg Department of Sociology and Work Science, Box 720 405 30, Göteborg, Sweden Visiting address: Sprängkullsgatan 25, room F411 Sprängkullsgatan 25, room K109 +46 031-786 41 73 adel.da...@sociology.gu.se On Sun, Mar 8, 2015 at 12:46 AM, Jim Lemon <drjimle...@gmail.com> wrote: > Hi Adel, > Almost certainly because the device you were using doesn't support > transparency.Try it with a PDF device and check the resulting file in a PDF > reader: > > pdf("ad.pdf") > print(p) > dev.off() > > Jim > > > On Sun, Mar 8, 2015 at 4:39 AM, Adel <adel.da...@socav.gu.se> wrote: > >> Hi >> I am trying to activate the alpha argument to work, but for some reason it >> does not to play with me.
