[R] matrix in data.frame

Dear list!

I have run into a problem that seems very simple but I can't find any
solution to it (have searched the internet, help-files and "An introduction
to R" etc without any luck). The problem is the following: I would like to
create a data.frame with two components (columns), the first component being
a matrix and the second component a vector. Whatever I have tried so far, I
end up with a data.frame containing all the columns from the matrix plus the
vector which is not what I am after. I have seen this kind of data.frame
among R example datasets (oliveoil and yarn).

I would greatly appreciate some help with this problem!

Kind regards,
