[R] Stacking of vectors to form a column vector

[Olufemi Bolarinwa]

Thank you Jeff for your response.
My y1, y2, y3 are actually 3 columns in the data so I cannot use the c() function to concatenate them. I am confusing the "columns" with vectors. I actually meant columns.
Any help will be much appreciated
