r - VennDiagram without group names and with Arial font -

-

i have been requested redo following venn diagram in r arial font , without group names... looking @ venndiagram manual not see how can it...

this mwe:

#install.packages("venndiagram") library(venndiagram)  <- c(1,2,3,4,5,6) b <- c(4,5,6,7,8,9,10,11,12) c <- c(1,2,10,11,12,5,13,14,15,16)  venn.diagram(list("a" = a, "b" = b, "c" = c),                  fill = c("red", "blue", "green"), alpha = c(0.5, 0.5, 0.5),                  cat.cex = .75, cex = .75, lty =2, lwd =0.5, fontfamily ="serif",                  filename = "test.tiff", imagetype = "tiff",                  height = 3000, width = 3000, resolution = 1500, units = "px",                  main="title", main.pos=c(0.1,1.05), main.fontfamily="serif", main.cex=.75)

test image

is possible remove group names a, b, , c, , change font family arial, or should think approach instead of r?

besides, possible add color legend?

really rough guess, see:

fontfamily ="serif",

and:

main.fontfamily="serif"

try changing them arial , see if works. haven't got time check out @ computer right super fast guess.

to remove group names, change them assign them in array:

venn.diagram(list("a" = a, "b" = b, "c" = c)

here can possibly call them you'd like
