Burt table from word frequency list

Dear all,

I have a word frequency list from a corpus (say, in .csv), where the  
first column is a word and the second is the occurrence frequency of  
that word in the corpus. Is it possible to obtain a Burt table (a  
table crossing all words with each other, i.e., where rows and columns  
are the words) from that frequency list with R? I'm exploring the "ca"  
package but I'm not able to solve this detail.

Thank you very much!
