查找下在 /usr/lib/R/etc/ 下的 Renviron 文件中。找到这一行 R_LIBS_SITE=${R_LIBS_SITE-‘/home/user/Archive/software/R/x86_64-pc-linux-gnu-library/3.0/:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library’} 当然上面包含XXX的路径修改成你希望的存储目录即可。 修改之后的再次在R中运行 libPaths() 命令的结果是: > .libPaths() [1] “/home/user/Archive/software/R/x86_64-pc-linux-gnu-library/3.0” [2] “/usr/local/lib/R/site-library” [3] “/usr/lib/R/site-library” [4] “/usr/lib/R/library”
取txt文件值 data=read.table(“1.txt”,header=T) 读值 head(data) windows下 获取当前工作目录 getwd() 相对路径 setwd(“.\\Rsourse”) 上一级目录 setwd(“..\\”) 绝对路径 setwd(“D:\\MySpace\\机器学习\\R\\Rsourse”)
假如我们要导入C:\Users\user\Desktop路径下的test.csv文件，则输入代码： read.csv(file = “C:\\Users\\user\\Desktop\\test.csv”) 默认情况下，R语言会认为第一行的是数据的标题，假如你的数据的第一行其实并不是标题，那么可以输入代码： read.csv(file = “C:\\Users\\user\\Desktop\\test.csv”,header = F) 下面的代码会将数据赋给对象Mydata： Mydata<-read.csv(file = “C:\\Users\\user\\Desktop\\test.csv”,header = F) 要查看Mydata对象里的数据，直接输入Mydata就可以了： Mydata 原始txt数据中有a、b两列数据，并且它们以“;”号作为分隔符，则： read.table(file = “C:\\Users\\user\\Desktop\\test.txt”,header = T,sep=”;”) 假如分隔符是其他符号，例如百分号“%”，则代码修改为： read.table(file = “C:\\Users\\user\\Desktop\\test.txt”,header = T,sep=”%”)
