Hi all,

How can I create (and check the existence of) a directory in a R session under 
Windows(xp)?

Kind regards,

 I have tested in WinXP:

 [5] CONFIG.SYSDebug
 [7] debug.log Desktop.ini
 [9] Dic   Documents and Settings

 Dic is a folder
 any(dir(C:/)==Dic)
 [1] TRUE


 That are right?

You said the test was

any(dir('your path')==your folder)

Now, what did you mean by that?  The path C:/ is not the path to the 
folder named on the RHS.  And I believe you will find your test also gives 
TRUE for AUTOEXEC.BAT, which is not a directory.

That does not work, but fortunately R has file_test() for this purpose.
