Hi,

Yes. See ?rk.get.label .

You can use
    write.table(..., col.names=sapply(my.data, rk.get.label))
(substitute "my.data" with the name of your data.frame).

In the development version of RKWard, I have just added a convenience function 
"rk.list.labels()" to make it easier to extract variable labels from a 
data.frame. Also, rk.get.label() now behaves better, in case no label has been 
assigned. If you would like to try the development version, see 
http://p.sf.net/rkward/svn .

Thomas
