Question

已关注 this post还有this link ，我尝试更新我的 R 版本。

 sessionInfo()
 R version 2.14.0 (2011-10-31)
 Platform: i386-pc-mingw32/i386 (32-bit)

 locale:
 [1] LC_COLLATE=English_United States.1252 
 [2] LC_CTYPE=English_United States.1252   
 [3] LC_MONETARY=English_United States.1252
 [4] LC_NUMERIC=C                          
 [5] LC_TIME=English_United States.1252    

 attached base packages:
 [1] stats     graphics  grDevices utils     datasets  methods   base     

 other attached packages:
 [1] installr_0.9

 loaded via a namespace (and not attached):
 [1] tools_2.14.0

但是当我运行代码时

  updateR()
  Error in file(con, "r") : cannot open the connection

运行以下命令时显示完全相同的错误:

 check.for.updates.R() # tells you if there is a new version of R or not.
 Error in file(con, "r") : cannot open the connection

 install.R() # download and run the latest R installer
 Error in file(con, "r") : cannot open the connection
