Dear all,
I'm writing code to do automatically several
calculations and gather the results in a matrix.
I have the following vectors and
I just want to make a matrix with them:
VD1
VD2
VD3
...
VD12
cbind( 1:12, matrix(c(VD1, ..., VD12), nrow=12, byrow=TRUE) )
or..
cbind( 1:12, rbind(VD1, ..., VD12) )
*In this case, this series of vectors stops there, in 12,
but it could be a higher number or smaller.
(for example: VD1, VD2 and VD3; only)
(or for example: VD1, VD2, ... till VD78)
All vectors have the same length, 9.
And vectors should be entered by row.
Besides, I would like to add a column with the number of the vector.
Something like this:
1 44 23 0.3 ...
2 51 27 0.8 ...
3 40 24 0.6 ...
4 47 18 0.2 ...
5 52 30 1.2 ...
... ... ... ... ...
12 39 22 0.5 ...
I hope I've explained myself good enough.
Thanks in advance for taking the time to help me.
