Hi,
My data.frame as follows;

   a          b                 c d
1 58009   2010-11-02 0 NA
2 114761 2011-07-28 1 2008-11-05
3 184440 2011-07-28 1 2009-12-08
4 189372 2011-07-28 0 NA
5 105286 NA              2 NA
6 186717 2011-07-28 0 NA
7 189106 2011-07-28 0 NA
8 127306 2011-07-28 0 NA
9 157342 2011-04-25 0 NA

Error in add.value.labels(test2$c, "alive", "dead", "missed") :
  unused argument(s) ("dead", "missed")

> add.value.labels(test2$c, "alive")
[1] 0 1 1 0 2 0 0 0 0
attr(,"value.labels")
alive  <NA>  <NA> 
    0     1     2

This function allows only one label. How can add second and other labels?

Thanks.
