Question

Edit:

Because I’m still struggleing with this, here’s additional information:

The matrix has the columns SessionID,UserID,query,[some time based parameters], length in words and length in chars

I want to get a frequency table of query and length, i.e. query, frequency of the query in matrix, length.

table(matrix$query,matrix$length) 

yields a table without showing the actual queryname and a whole lot of columns

How do I use table() right to get the table I want?

Answer 1

I think you can use the table function: it is quite fast and will give the frequency of each query (you can alsos sort it), e.g.:

sort(table(mat[,"query"]))
