Dear all,

I have the following matrix.
A A A A A A A A A A
    [1,] 0 0 0 0 0 0 0 0 0 0
    [2,] 0 0 0 0 0 0 0 0 0 1
    [3,] 0 0 0 0 0 0 0 0 0 2

How can I change it into:
         [,1]  [,2]  [,3]  [,4]  [,5]  [,6]  [,7]  [,8]   [,9]   [,10]
    [1,] 0     0     0      0     0     0     0     0     0       0
    [2,] 0     0     0      0     0     0     0     0     0       1
    [3,] 0     0     0      0     0     0     0     0     0        2


I tried:
But failed.

Hi Gundala,

try chopping off the top row like
newx<-as.matrix(x[2:dim(x)[1],])

OR

try changing it to a data frame...
new x<-data.frame(x,row.names=NULL)

#pretty sure its not row.names but there is probably an equivalent for 
col.names

OR

look into ?read.table and specify header = F

Cheers, Si.

Hello,

colnames( dat ) <- NULL

will do the trick.
