Hi I am trying to activate the alpha argument to work, but for some reason it does not to play with me. Anybody has an idea why?
p <- ggplot(data = prediction_df, aes(x=x, y=prediction, fill=threshold)) + geom_area(colour="black", size=.2, alpha=.4) + scale_fill_brewer(palette="Set1", breaks=rev(levels(prediction_df$threshold))) p + geom_rect(aes(xmin=2, xmax=10, ymin=(0), ymax=(1)), fill="black", alpha=0.5) prediction_df x prediction threshold 1 -10 0.5694161 noAF 2 -9 0.5700513 noAF 3 -8 0.5706863 noAF 4 -7 0.5713211 noAF 5 -6 0.5719556 noAF 6 -5 0.5725899 noAF 7 -4 0.5732240 noAF 8 -3 0.5738578 noAF 9 -2 0.5744914 noAF 10 -1 0.5751247 noAF 11 0 0.5757578 noAF 12 1 0.5763906 noAF 13 2 0.5770232 noAF 14 3 0.5776556 noAF 15 4 0.5782876 noAF 16 5 0.5789195 noAF 17 6 0.5795510 noAF 18 7 0.5801823 noAF 19 8 0.5808134 noAF 20 9 0.5814441 noAF 21 10 0.5820747 noAF 22 -10 0.2359140 singleAF 23 -9 0.2356847 singleAF 24 -8 0.2354550 singleAF 25 -7 0.2352249 singleAF 26 -6 0.2349943 singleAF 27 -5 0.2347634 singleAF 28 -4 0.2345321 singleAF 29 -3 0.2343003 singleAF 30 -2 0.2340682 singleAF 31 -1 0.2338356 singleAF 32 0 0.2336027 singleAF 33 1 0.2333694 singleAF 34 2 0.2331357 singleAF 35 3 0.2329016 singleAF 36 4 0.2326671 singleAF 37 5 0.2324322 singleAF 38 6 0.2321969 singleAF 39 7 0.2319613 singleAF 40 8 0.2317253 singleAF 41 9 0.2314889 singleAF 42 10 0.2312522 singleAF 43 -10 0.1946699 multipleAF 44 -9 0.1942640 multipleAF 45 -8 0.1938587 multipleAF 46 -7 0.1934540 multipleAF 47 -6 0.1930500 multipleAF 48 -5 0.1926467 multipleAF 49 -4 0.1922440 multipleAF 50 -3 0.1918419 multipleAF 51 -2 0.1914404 multipleAF 52 -1 0.1910397 multipleAF 53 0 0.1906395 multipleAF 54 1 0.1902400 multipleAF 55 2 0.1898411 multipleAF 56 3 0.1894429 multipleAF 57 4 0.1890453 multipleAF 58 5 0.1886483 multipleAF 59 6 0.1882520 multipleAF 60 7 0.1878564 multipleAF 61 8 0.1874613 multipleAF 62 9 0.1870669 multipleAF 63 10 0.1866732 multipleAF -- View this message in context: http://r.789695.n4.nabble.com/Alpha-not-working-in-geom-rect-tp4704291.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
