[R] Can not save files

[John Sorkin]

David,
I checked getwd()
and tried to save to the directory. It did not work:


> getwd()
[1] "C:/Users/John/Documents"
> save(TheResults,file="c:\\users\\john\\documents")
Error in gzfile(file, "wb") : cannot open the connection
In addition: Warning message:
In gzfile(file, "wb") :
  cannot open compressed file 'c:\users\john\documents', probable reason
'Permission denied'
> 


Any thoughts?


Thanks,
John

Because your OS does not allow you to save things there. Since you are
specifying an absolute path, R is not using your working directory. You
may want to read the help pages for:

?normalizePath
?getwd

Permissions are not available on your machine at the Windows equivalent
of the "root". You should educate yourself about your operating system.
