设置工作路径:打开Rstudio→Session→Set Working Directory→Choose Directory,然后选择你刚才保存文件的文件夹,也可以直接setwd("~/Dropbox/xxx") 画图 ##加载ggplot2包library(ggplot2)##读取刚才保存的富集分析结果文件goinput<-read.table("test.txt",header=T,sep="\t")##header = T 第一行是表头,sep ...
When we are working with large sets of numbers it can be useful to display that information graphically to gain more insight. Visualization deserves an entire course of its own (there is that much to know!). If you are interested in learning about plotting with base R functions, we have ...
While working through these examples you will be introduced to all six components of the grammar, which are then defined more precisely in Section 3.5. The chapter concludes with Section 3.6, which describes how the various components map to data structures in R. 这章首先详述简单图形的绘制过程:...
