Re: [R] Open a file which name contains a tilde

Hi John, First, the unix and linux filesystem allows the use of any nonzero character in its filesystem filenames and the c functions open / fopen, symlink. rename, chdir and so on don't care about any tilde. If the open systemcall gets a file which begins with a tilde then it will try to open

Re: [R] Open a file which name contains a tilde

?path.expand Expand a path name, for example by replacing a leading tilde by the user's home directory (if defined on that platform). *A* path name. The argument is a character vector. If multiple path names are passed, they are passed On most builds of R *A LEADING* "~user" will be
