问题：

#如果没有设置全局的目录直接读取文件就找不到目录

#attempt to read in CSV file
df <- read.csv('data.csv')

解决：

第一，使用绝对路径(完整路径)

df <- read.csv('C:\\Users\\test\\Desktop\\data.csv', header=TRUE, stringsAsFactors=FALSE)

第二，配置程序环境的全局指定目录：

#display current directory
getwd()

[1] "C:/Users/xxx/Documents"


#set current directory
setwd('C:\\Users\\test\\Desktop')

完整错误：
