[R] question regarding conversion from factor to vector

Hello,

let me show you the following part of a session:

As you can see, the values of column "singles" of dataframe E show
a strong regularity w.r.t. multiples of 7, and with the second line
I checked that.

Now I hope that there is a better way to get the vector of values out
of the table-result? First I convert it into a dataframe, to get a
name for the two vectors constituting the table, then a get a vector
of strings(!), which are then converted to integers.

By the way, the type of E$singles is integers.

Thanks for your help!
