在R中导出为CSV时,权限被拒绝

Question

这是我试过的代码,我尝试了方法.基本上我只是想知道被拒绝的部分.

 data <- matrix(c(1,2,3,4), ncol=2)
 write.csv(data,"C:/Users/brian_000/Documents")

错误:

Error in file(file, ifelse(append, "a", "w")) : 
  cannot open the connection
 In addition: Warning message:
 In file(file, ifelse(append, "a", "w")) :
   cannot open file 'C:/Users/brian_000/Documents': Permission denied
   write.csv(data, file="C:/Users/brian_000/Documents")
  Error in file(file, ifelse(append, "a", "w")) : 
 cannot open the connection
 In addition: Warning message:
 In file(file, ifelse(append, "a", "w")) :
  cannot open file 'C:/Users/brian_000/Documents': Permission denied

Answer 1

C:/Users/brian_000/Documents是(大概)一个目录,所以你不能写它就像一个文件.相反,写入一个文件,如C:/Users/brian_000/Documents/myfile.csv.
