venn-diagram

I would like to create a legend for a venneuler venn diagram. This should be straight forward because the function venneuler returns the colors used to the console. The colors are of a value between 0 and 1. I want to know how to turn those numberic values stored in $colors into something I can use to fill the fill argument in legend. I have attempted this below by using the $colors extracted from venneuler and indexing from colors(). I know this is not correct because colors() is indexed with interval values but put it in to show what I'd like. set.seed(20) x <- matrix(sample(0:1, 100,

I have made a three way venn diagram. I have three issues with it that I can't seem to solve. What is the code to move the circle labels (i.e."Set1","Set2","Set3") because right now one is too far away from the circle. What is the code to make the circles be three equal sizes/change the circle size? What is the code to move the circles around the plot. Right now, set2 is within set3 (but coloured differently), I would like the diagram to look more like the "standard" way of showing a venn diagram (i.e. 3 separate circles with some overlap in the middle). On another note, I found it difficult

I am using "calculate.overlap" function in R package "VennDiagram". I am comparing four sets of data as following: library(VennDiagram) overlap=calculate.overlap( x=list( "1"=1, "2"=2, "3"=3, "4"=4 ) ) The output file "overlap" consists of 15 lists. They are called: $a6, a12, a11... How do I know which list belongs to which comparison? CandicePHChu By replacing x in overlap[[x]] with red number 1-15, you can get a complete list of genes of interest at the specific location in Venn diagram. Also, you can get the numbers of genes by using length() function. seanyun Sorry, I need to point out

I am running an analysis of a number of sets and I have been using the package VennDiagram, which has been working just fine, but it only handles up to 5 sets, and now it turns out that I need to look at 6 or more sets. Ideally, I'm looking for a something that can do this (below) with 6 or more sets, but it doesn't necessarily have to have a plot function as long as the counts can be retrieved: Any ideas of what I can do to add one or more sets to these five and still get the counts? Thanks! Here's an attempt: list1 <- c("a","b","c","e") list2 <- c("a","b","c","e") list3 <- c("a","b") list4 <

I found many resources on how to draw Venn diagrams in R. Stack Overflow has a lot of them . However, I still can't draw my diagrams the way I want. Take the following code as an example: library("VennDiagram") A <- 1:4 B <- 3:6 d <- list(A, B) vp <- venn.diagram(d, fill = c("white", "white"), alpha = 1, filename = NULL, category.names=c("A", "B")) grid.draw(vp) I want the intersection between the sets to be red. However, if I change any of the white colors to red, I get the following: vp_red <- venn.diagram(d, fill = c("red", "white"), alpha = 1, filename = NULL, category.names=c("A", "B"))
