R语言的3个简单作图

R语言多组箱线图

a<-read.csv("data.csv");

par(mfrow=c(3,2), mar=c(2,2,2,2)); 分区画图，mfrow：3行2列，mar每组图的边界设置。

for(i in 1:6){
boxplot(a[(i*2):(i*2+1)],range=1.5,width=NULL,varwidth=FALSE,notch= FALSE,outline=TRUE,names(a[(i*2):(i*2+1)]),plot=TRUE,col=c("green","orange"),log="",horizontal=FALSE,add=FALSE,at=NULL);}

R语言相关系数图

a <- read.table("r-value.txt",header=T,row.names= 1); 相关系数值，有标题行和列

b<-read.table("p-value.txt",header=T,row.names= 1); 相关系数P值，有标题行和列

pmat=apply(b,2,as.numeric);

d=apply(a,2,as.numeric);

rownames(d)<-rownames(a);

library(corrplot);

corrplot(d,method="ellipse",mar=c(0,0,0,0),tl.col="black",addCoef.col="black",tl.srt=0,tl.cex=1,cl.pos="n", p.mat=pmat,sig.level=0.05,insig=c("blank"),number.cex=1,number.font=4);

R语言韦恩图

##加载VennDiagram软件包

> library (VennDiagram)

例1：

##生成三个不同的组合

> A <- c("C", "D", "B", "E")

> B <- c("C", "E", "B", "A")

> C <- c("C", "E", "X", "Y")

##使用venn.diagram功能绘图

> venn.diagram(x=list(Tumor=A, Organoids=B, Primary=C), "My1.png", height = 450, width = 450, resolution =300, imagetype="png", col="white", fill=c(colors()[616], colors()[38], colors()[468]), alpha=c(0.6, 0.6, 0.6), lwd=c(1, 1, 1), cex=0, cat.dist=c(-0.07, -0.07, -0.05), cat.pos=c(300, 60, 180), cat.cex=0.45)

例2：

##生成三个不同的组合

> D <- c("C", "D", "B", "E")

> E <- c("C", "F", "G", "K")

> F <- c("C", "H", "X", "Y")

##使用venn.diagram功能绘图

> venn.diagram(x=list(Tumor=D, Organoids=F,Primary=E), "My2.png", height = 450, width = 450, resolution =300, imagetype="png", col="gray",fill=c(colors()[148], colors()[589], colors()[116]), alpha=c(0.6, 0.6, 0.6), lwd=0.5, cex=0, cat.dist=c(-0.07, -0.07, -0.05), cat.pos=c(100, 260, 0),cat.cex=0.45, cat.col="black", rotation.degree=180)

例3：

##生成四个不同的组合

> A<- sample(1:1000, 400, replace = FALSE)

> B<- sample(1:1000, 600, replace = FALSE)

> C<- sample(1:1000, 350, replace = FALSE)

> D<- sample(1:1000, 550, replace = FALSE)

##使用venn.diagram功能绘图

> venn.diagram(x= list(A = A,D = D,B = B,C = C), filename = "My3.png", height = 450, width = 450,resolution =300, imagetype="png", col ="transparent", fill =c("cornflowerblue","green","yellow","darkorchid1"),alpha = 0.5, label.col = c("orange", "white","darkorchid4", "white", "white", "white",    "white", "white","darkblue", "white", "white", "white","white", "darkgreen", "white"), cex = 0.45,fontfamily = "serif", fontface = "bold",cat.col =c("darkblue", "darkgreen", "orange","darkorchid4"), cat.cex = 0.45,cat.pos = 0, cat.dist = 0.07,cat.fontfamily = "serif", rotation.degree = 270)

例4：

##生成四个不同的组合

> A<- sample(LETTERS, 18, replace = FALSE)

> B<- sample(LETTERS, 20, replace = FALSE)

> C<- sample(LETTERS, 22, replace = FALSE)

> D<- sample(LETTERS, 19, replace = FALSE)

##使用venn.diagram功能绘图

> venn.diagram(x= list(A = A,D = D,B = B,C = C), filename = "My4.png", height = 450, width = 450,resolution =300, imagetype="png", col="transparent",fill=c("cornflowerblue","green","yellow","darkorchid1"),alpha = 0.50, cex=0.45, cat.cex=0.45)

> venn.diagram(x =list(A = A,D = D,B = B,C = C), filename = "My5.png", height = 450, width= 450, resolution =300, imagetype="png", lwd=0.6, fill =c("cornflowerblue","green","yellow","darkorchid1"),cex=0.45, cat.cex=0.45)
