[R] Matrix for correlation

[Geophagus]

hi @ all,
I have problem with creating a matrix for a cor() function.
I try to use the cor() function on a matrix to test the correlation between
each value in a column.
Maybe like corr(x, method = xyz).
My x has two columns maybe like this:

MEDIA  VALUE
Car      23
Train    26
Plane   25
Cab     22
Bike     15

.... and so on.

Now I want to calculate the correlation between Car and Train, Car and
Plane, Train and Plane and so on.

Sorry but I don't have a clue and I hope there is an easy way to solve my
problem.
Thanks a lot for all answers.

Greetz Geo
