[BioC] Set plot title and background in makeVennDiagram (ChIPpeakAnno)

[Zhu, Lihua (Julie)]

Antonio,

Thanks to Jianhong, options from package VennDiagram are now available in ChIPpeakAnno:::makeVennDiagram (version 2.5.12).  You can specify the title using main and background color using fill. For more options, please type ?venn.diagram.

Here is an example by Jianhong,

peaks1 = RangedData(IRanges(start = c(967654, 2010897, 2496704),
    end = c(967754, 2010997, 2496804), names = c("Site1", "Site2", "Site3")),
    space = c("1", "2", "3"), strand=as.integer(1),feature=c("a","b","f"))
peaks2 = RangedData(IRanges(start = c(967659, 2010898,2496700,3075866,3123260),
    end = c(967869, 2011108, 2496920, 3076166, 3123470),
    names = c("t1", "t2", "t3", "t4", "t5")),
    space = c("1", "2", "3", "1", "2"), strand = c(1, 1, -1,-1,1), feature=c("a","b","c","d","a"))
makeVennDiagram(RangedDataList(peaks1,peaks2, peaks1, peaks2), NameOfPeaks=c("TF1", "TF2","TF3", "TF4"),
     totalTest=100,useFeature=TRUE, main="Venn Diagram",
    col = "transparent",fill = c("cornflowerblue", "green", "yellow", "darkorchid1"),
    alpha = 0.50,label.col = c("orange", "white", "darkorchid4", "white", "white", "white", "white", "white", "darkblue", "white", "white", "white", "white", "darkgreen", "white"), cat.col = c("darkblue", "darkgreen", "orange", "darkorchid4"))


Best regards,

Julie

Hi Julie,

Thanks!

If it is not asking too much and how much work it takes, but adding colours to the background of the circles would also be nice for presentations and papers. Basically some possibilities along the lines of the R package VennDiagram (http://www.biomedcentral.com/1471-2105/12/35)

Good package you've developed btw.

Anotonio,

Thanks for the great suggestion! Currently makeVennDiagram only supports
limited plotting options, i.e., cex and count.col. I will add the title in
my to do list.

Best regards,

Julie
