Hi all,
if I transpose a matrix with t(data), the newly created colums do
not appear to have the first row as header. How can I do to have all
the newly created columns have their first row as a header?
The term "header" doesn't really have meaning in R with reference to
matrices. And the analog that might make sense, column names, fails to
behave in the manner of your complaint.

a b c
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
> t(M)
[,1] [,2] [,3]
a 1 2 3
b 4 5 6
c 7 8 9
So exactly _what_ is your problem?
