维恩图(Venn diagram)是一种用于可视化集合之间关系的图表。在R语言中,可以使用一些包来创建维恩图,如venneuler
、VennDiagram
和eulerr
等。
venneuler
包创建维恩图:# 安装venneuler包
install.packages("venneuler")
# 加载venneuler包
library(venneuler)
# 创建维恩图数据
sets <- list(A = c("apple", "banana", "cherry"),
B = c("banana", "durian", "elderberry"),
C = c("cherry", "durian", "fig"))
# 创建维恩图
venn <- venneuler(sets)
# 绘制维恩图
plot(venn)
VennDiagram
包创建维恩图:# 安装VennDiagram包
install.packages("VennDiagram")
# 加载VennDiagram包
library(VennDiagram)
# 创建维恩图数据
set1 <- c("apple", "banana", "cherry")
set2 <- c("banana", "durian", "elderberry")
set3 <- c("cherry", "durian", "fig")
# 创建维恩图
venn.diagram(x = list(A = set1, B = set2, C = set3),
filename = NULL,
output = TRUE,
imagetype = "png",
main = "Venn Diagram",
main.cex = 2,
fill = c("red", "blue", "green"),
alpha = 0.5,
label.col = c("black", "white", "darkblue"),
cex = 1.5,
fontfamily = "serif",
cat.col = c("red", "blue", "green"),
cat.cex = 1.5,
cat.fontfamily = "serif",
cat.dist = c(0.03, 0.03, 0.03),
cat.pos = c(-15, 15, 0),
cat.just = list(c(0.5, 0.5), c(0.5, 0.5), c(0.5, 0.5)),
rotation.degree = 0,
margin = 0.1,
euler.d = TRUE,
scaled = FALSE,
ind = TRUE,
ext.text = FALSE,
ext.line = FALSE,
ext.length = 0.1,
ext.pos = 1,
ext.dist = -0.05,
ext.line.lwd = 1,
ext.line.lty = "solid",
ext.line.col = "black",
lwd = 1,
lty = "solid",
col = "black",
fill.alpha = 0.5,
cex.prop = 1,
sep.dist = 0.03,
sep.lty = "dashed",
sep.col = "black",
cat.sep = 0.03,
cat.lty = "dashed",
cat.col = "black",
cat.fontfamily = "serif",
cat.cex = 1.5,
rotation.cw = TRUE,
rotation.degree = 90,
rotation.ylim = NULL,
rotation.xlim = NULL,
rotation.factor = 1,
rotation.fun = NULL,
rotation.control = list(),
zscore = NULL,
zscore.col = "red",
zscore.lty = "dashed",
zscore.lwd = 1,
zscore.cex = 1.5,
zscore.fontfamily = "serif",
zscore.dist = 0.03,
zscore.pos = 1,
zscore.side = "both",
zscore.prop = 0.1,
zscore.cex.prop = 1,
zscore.sep.dist = 0.03,
zscore.sep.lty = "dashed",
zscore.sep.col = "black",
zscore.cat.sep = 0.03,
zscore.cat.lty = "dashed",
zscore.cat.col = "black",
zscore.cat.fontfamily = "serif",
zscore.cat.cex = 1.5,
zscore.rotation.cw = TRUE,
zscore.rotation.degree = 90,
zscore.rotation.ylim = NULL,
zscore.rotation.xlim = NULL,
zscore.rotation.factor = 1,
zscore.rotation.fun = NULL,
zscore.rotation.control = list())
以上是使用venneuler
和VennDiagram
包创建维恩图的示例代码。你可以根据自己的需求选择其中一种方式来创建维恩图,并根据具体的数据和参数进行调整。
