Hi All,
I would like to create a matrix in R but I dont know the size of my matrix. I
only know the size of the columns but not the size of the rows. So, is there
any way to create a dynamic matrix of size NULL by n_cols? and then add to that
matrix?
I know for a vector, I can do this: x= NULL but is there any way to do the same
for a matrix as well?
Thanks a lot,Andra
