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
10
x$b
[1] 1 2 3 4 5

You need to use I() or something similar. E.g.
A - matrix(1:6, 2,3)
data.frame(x=1:2, I(A))
X - data.frame(x=1:2)
X$A - A
both insert A as a single column.
