We’re so happy to announce the release of ggplot2 3.3.0 on CRAN. But this function works fine if you’re happy with the default ggplot2 colors for discrete variables. The zoomed-in area will be indicated on the full dataset panel for reference. This vignette documents the official extension mechanism provided in ggplot2 2.0.0. Reply. Could you imagine a shorter version of this code for making the by-gene plot? could not find function "initRefFields" I found on internet that the solution for this problem is upgrading to a newer version of R (and indeed, on 2.15 or 3.0 ggplot2 works fine).

Assuming that you have saved your plot in an object called p: p + scale_y_continuous(breaks = seq(0, 1, by = .1)) Good luck, Edwin.
