Hi is there anyone who could direct me on how i could stack my data without increasing the length of the output. i have tried to use the stack function but apparently, the length of the resultant is larger than the input. i have attached a file of 10 columns and each column has a length of 15493 records. i would wish to stack all the 10 into 1 with a length of 15493. Is there something that can be done?
