Hi all, I finally managed to get Vennerable working with the help I got on the forum. However, I'm faced with my next challange now. The easy way to work with Vennerable works just fine, that is, if I enter code like this: Vdemo2 <- Venn(SetNames = c("foo", "bar"), Weight = c(`01`= 7, '11' = 8, '10' = 12)) What I would like to do is the following: I have sequence data that I need to compare between 3 or 4 samples. For example sequence 1 is found in samples 1 and 2, sequence 2 is only found in sample 3, ... This gives me a list of sequences present in each sample. I would like to have these lists read in R as input for Vennerable, giving me a Venn Diagram as output, preferably with weight and colors. I believe I'd have to do something like this: Set1 <- c(1,2,3,4,5,6,7,8,9,10) Set2 <- c(1,2,5,6,11,12,13,14) Set3 <- c(2,6,11,12,15,16,17) And afterwards, based on these sets, the matrix has to be generated so I get a nice plot of my data. Hopefully anyone can help with this? Your help would be greatly appreciated!
