R help - Oct 2006 - Merging tables of differing lengths

Hi,
   I  am  using the table() function on two different vectors to obtain a
   frequency distribution for each:
   >tabtyp1 <- table(wintype1)
   >tabtyp2 <- table(wintype2)
   The resulting tables look like this:
   > tabtyp1 <- table(wintype1)
   > tabtyp2 <- table(wintype2)
   > tabtyp1
   wintype1
       0     2     3     4     5     6     7     8
   16826 10031  1636   797   239   399    63     6
   > tabtyp2
   wintype2
       0     2     3     4     5     6     7     8    10
   16857 10012  1703   788   171   375    77    14     3
   What I want to do is merge these two tables into a 2X10 table in order
   to  do a chi-square test.  Given the unequal number of columns, all my
   attempts  are failing.  I am also having instances where the number of
   columns is the same, but the values are different, e.g., one table has
   values  for  7  and  not  8,  while the other lacks 7s but has 8s. Any
   suggestions?

You might want to try something like:

levs <- unique(c(wintype1, wintype2))
table(factor(wintype1, levels=lev))
table(factor(wintype2, levels=lev))
