R help - Oct 2006 - convert vector to matrix

Hi All,
   
   
  I have vector containing 10 elements(odservations). I need to put this into a
matrix, where the matrix should contain only one column.
I need this to be done using the cbind command because in the final table I
should have a column of attributes( from adifferent vector) and a column of
vectors from the matrix above

  Please suggest me how this can be done
   
  Thanks and Regards,
  Pratap

Did you even try to use cbind on your vector? I guess not as,
> vec <- 1:10
> mat <- cbind(vec)
> mat
      vec
 [1,]   1
 [2,]   2
 [3,]   3
 [4,]   4
 [5,]   5
 [6,]   6
 [7,]   7
 [8,]   8
 [9,]   9
[10,]  10
> class(mat)
[1] "matrix"

clearly shows it is possible.

Why does mat remain a matrix instead of "losing" one dimension?
I am reading the FAQ at...
http://cran.us.r-project.org/doc/FAQ/R-FAQ.html#Why-do-my-matrices-lose-
dimensions_003f
... and it seems that anything you do to mat should turn it back
into a one-dimensional vector.
