Hi, 

I am working on categorical data with column as disease name(categaory).

My input data is
 [1] Acute lymphoblastic leukemia (childhood)
 [2] Adiponectin levels                     
 [3] Adiponectin levels                     
 [4] Adiponectin levels                     
 [5] Adiponectin levels                     
 [6] Adiponectin levels                     
 [7] Adiposity                              
 [8] Adiposity                              
 [9] Adiposity                              
[10] Adiposity                              
[11] Age-related macular degeneration       
[12] Age-related macular degeneration       
[13] Aging (time to death)                  
[14] Aging (time to event)                  
[15] Aging (time to event)                  
[16] Aging (time to event)                  
[17] Aging (time to event)                  
[18] AIDS                                   
[19] AIDS                                   
[20] AIDS
.....


when i use table command, i get

                                                                                                                
[,1]
Acute lymphoblastic leukemia (childhood)                             1
Adiponectin levels                                                                            
5
Adiposity                                                                                              
4
Age-related macular degeneration                                           
2
Aging (time to death)                                                                      
1
......

But i need to sort this table by frequency and need to plot a histogram with
lable first column (e.g. Adiposity , Age-related macular degeneration  as
bar name). How can i do it?

Regards
