Hello, I’m working with cummeRbund in R 3.1.1 and I’m trying to get a different point size for my csVolcano plot. I’ve tried two approaches an neither see to work.
after loading library and the data as library(cummeRbund) cuff <- readCufflinks(“diff_out”) 1)use the mapping setting for the csVoclano function v <- csVolcano(genes(cuff), “EP”, “PC”, showSignificant=TRUE, alpha=0.05, mapping=aes(size=5)) When I view this the point size stays a the default settings. 2) Alter the ggplot2 information after creating the plot t <- v + geom_point(aes(size = 2)) This produces an error saying that “geom_point requires the following missing aesthetics: x, y if I provide those labels the points still don’t change t <- v + geom_point(aes(x=log10 y=log2 size =2)) Using method two with csScatter works great and the points change size. What am I missing? Cheers Ian _______________________________________________ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
