Hi!
I need some help to finish my script.

I have two tables that I combine randomly to produce a third table.  
This I do for hundreds of iterations. In the output file I get all the  
simulated tables after each other. It looks like this (in this case 3  
iterations):

output file:

Now I would like to compare one of the tables used to create the  
output tables with every output table, one after the other. In detail,  
I am comparing row 1 of the "creator" table with row 1 of the first  
output table and then row 2 of the "creator" table with row 2 of the  
first output table and so on until row 27 and each row for all  
columns. Then, when the first output table is finished I go on  
comparing the first "creator" table with the second table in the  
output, row for row for all columns. I do this for all iterations.

The first "creator" table is called "data_mc".

# apply similarity function (lettermatch) to my data
for (i in 1:(nrow(data_mc))){
   for (y in 1:(ncol(data_mc))) {
         creator_table <- data_mc[data_mc$Status=="mother",y]
         output_tables <- ???
         output[i,y]<-(lettermatch(creator_table, output_tables))
   }
}

Could you please help me how I have to call up the output tables in  
the way I need them (described above) for the function "lettermatch"?  
Maybe I need to change the format of the output file?

Thank you.
Laetitia
