[R] filehash

[Prof Brian Ripley]

I suspect you have a file permission problem, and noticed filehash has 
some bugs which would mask this.  E.g. it does

createDB1 <- function(dbName) {
     if(!hasWorkingFtell())
         stop("need working 'ftell()' to use 'DB1' format")
     if(!file.exists(dbName))
         file.create(dbName)
     else
         message(gettextf("database '%s' already exists", dbName))
     TRUE
}

and so fails to check that file.create succeeded, and calls message() 
on an already translated message without 'domain=NA'.  (It also calls 
dir.create without checking the result.)

As far as I can see filehash will try to create a file in the current 
working directory.  Did you set up the shortcut as dscribed in the rw-FAQ 
so that the working directory was owned by you?
