Is there a way to generate a variable based on a string variable that contains numbers in a list? For example, I have a string variable like 'contact_autism' below and I'd like to create a binary variable like 'contact_autism1' equal to 1 for observations of contact_autism that contain 6. Thanks
Contact_autism Contact_autism1
