[R] How to delete Locked files in Mac

[Christofer Bogaso]

Hi,

I am looking for some R code, which will delete all files in a Folder
that contains both Locked and Unlocked files. There are many,
therefore i would like to delete all files programmatically in one go.

I used following code :

## "SS" is the Folder name including entire path which contains Locked
and Unlocked files.

file.remove(file.path(ss, list.files(ss)))
[1] FALSE
Warning messages:
1: In file.remove(file.path(ss, list.files(ss))) :
  cannot remove file '..... my folder path...', reason 'Read-only file system'

Also when I tried to delete a single Locked file, I am getting following error:

Warning message:
In file.remove(ss1) :
  cannot remove file '/..... my folder path...', reason 'Operation not
permitted'

I am using Mac with OS : 10.7.5

Could you please help me with correct R code?
