VennDiagram，不带组名，带有Arial字体 [英] VennDiagram without group names and with Arial font

问题描述

已要求我使用Arial字体且不使用组名重做R中的以下Venn图...查看

I have been requested to redo the following Venn diagram in R with Arial font and without the group names... Looking at VennDiagram manual I do not see how I can do it...

这是我的MWE:

#install.packages("VennDiagram")
library(VennDiagram)

a <- 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)

是否甚至可以删除组名A，B和C，并将字体系列更改为Arial，还是我应该考虑另一种方法而不是R?

Is it even possible to remove the group names A, B, and C, and change the font family to Arial, or I should think about another approach instead of R?

此外，是否可以添加颜色图例?

Besides, could it be possible to add a color legend?

推荐答案

要安装Arial字体，请使用此和main.fontfamily="serif".

To install Arial fonts, use this manual. Then you should be able to change fontfamily ="Arial" and main.fontfamily="serif".
