when i run your code i get the exact same output but why doesn't is work with my code?

Cellcykel <-read.csv2(file.choose(),header = FALSE)      
cclist <- Cellcykel$V1                                  
cclist
length(cclist)

zd <-read.csv2(file.choose(),header = FALSE)              
ZDlist <- zd$V1                                           
ZDlist
length(ZDlist)


install.packages("VennDiagram")                           

venn.diagram(list("Cellcykel"=cclist, "ZD"=ZDlist),
             fill = c("cyan","red"),
             cex= 1.5,
             filename = "C-mot-.ZD.png",
             print.mode =c("raw", "percent"))

overlap <- intersect(cclist, ZDlist)
overlap

cat(paste0(overlap, collapse = "\n"))

what am i doing wrong?
