[R] How to include "NA" level in table funcion.

[Guoqiang Wang]

Thanks for all your help from R network.

I really feel at home here.

The problem of long string has been solved, by
following the 'paste' suggestion.

Now I have another problem. I try to make a cross
table of the following dataset.
---------------------------------------------
> summary(bor.fac)
 cell     response    resp.mth         income       
age          province   
 1:4352   0:3122   Min.   :0.000   0-31k  :1475   0-21

 2:1916   1:3146   1st Qu.:0.000   31k-43k:1562  
21-34:1659   BC     : 700  
                   Median :1.000   43k-59k:1567  
34-41:1568   AB     : 459  
                   Mean   :1.316   59k-75k: 905  
41-49:1438   NS     : 303  
                   3rd Qu.:3.000   75k+   : 662   49+ 
:1601   MB     : 297  
                   Max.   :6.000   NA's   :  97       
        NB     : 180  
                                                      
        (Other): 265  
       tenure        acctcnt             fundsp    
ont     
 0-0.67   :  16   Min.   : 0.000   0-1.5k   :1404  
0:2204  
 0.67-1.5 :1645   1st Qu.: 3.000   1.5k-4.4k:1568  
1:4064  
 1.5-1.92 :1775   Median : 3.000   4.4k-10k :1566     
     
 1.92-2.33:1218   Mean   : 3.169   10k+     :1567     
     
 2.33+    :1614   3rd Qu.: 4.000   NA's     : 163     
     
                  Max.   :13.000                     

----------------------------------------
If I use table functions, the level "NA's" in income
and "other" in acctcnt won't appear in the table
regardless of my efforts.

> table(income, response,cell, exclude=(""))
, , cell = 1

         response
income      0   1
  0-31k   459 585
  31k-43k 524 544
  43k-59k 553 527
  59k-75k 350 290
  75k+    239 201

, , cell = 2

         response
income      0   1
  0-31k   214 217
  31k-43k 242 252
  43k-59k 239 248
  59k-75k 135 130
  75k+    108 114

> table(income, response,cell, exclude=F)
, , cell = 1

         response
income      0   1
  0-31k   459 585
  31k-43k 524 544
  43k-59k 553 527
  59k-75k 350 290
  75k+    239 201

, , cell = 2

         response
income      0   1
  0-31k   214 217
  31k-43k 242 252
  43k-59k 239 248
  59k-75k 135 130
  75k+    108 114
-------------------------------------------------
How can I include "NA" and "other" in the table?

Thanks you so much.
