如果我们想不断遍历所有的基因,aes里面填写是参数,而我们通常填入的列名是character,这个时候用到字符向量的循环,将aes改成aes_string,它可以将字符变量映射为ggplot所需的输入参数。ggplot里面的其他变量也要改成字符串的形式,即可以很容易的实现循环出图。 即 写成一个function,适用于下次直接进行基因表达查询
后图非常臃肿,突然产生一个想法如何只对图形进行聚类但不显示聚类树,下面通过一个小例子来展示 ❞ 加载R包 主要使用ggdendro中的函数dendro_data来提取聚类标签 library(tidyverse) # install.packages("ggdendro") library(ggdendro) library(aplot) 导入数据 df <- read_tsv("data.xls") %>% column_to_row...
The annotate() function allows to add all kind of shape on a ggplot2 chart. The first argument will control what kind is used: rect or segment for rectangle, segment or arrow. # Add rectangles p + annotate("rect", xmin=c(2,4), xmax=c(3,5), ymin=c(20,10) , ymax=c(30,20...
方法一、显示观察数量+平均值 写个简单的函数即可,利用length(x)函数统计数量、mean(x)函数计算平均值。废话不讲了,直接上代码: #functionfornumberofobservationsgive.n<-function(x){return(c(y=median(x)*1.05,label=length(x)))#experimentwiththemultipliertofindtheperfectposition}#y=median(x)*1.05是观察...
