Hi everyone, I have a question about how to use a for loop to create new columns based on information I have in my rows. It seems easy but I am working with data where every row represents a follow up appointment. Every person has a follow up id (i.e. the follow up id is 1 in every row that corresponds to the same person) so there are duplicated people in the rows, but each row has new information on that specific person.
What I want is to have every row represent a person, but I can't just remove the duplicated ID's because I want to keep the information. So, is there a way to move the information from the rows into new columns that represent follow ups? (i.e. follow up 1 patient status, follow up 1 date, follow up 2 patient status, follow up 2 date, etc)
I currently have 10 columns in my data set and I know that is going to increase a lot if I do this. I'm sure I can use a nested for loop to do this but I am fairly new to R and am having a hard time conceptualizing exactly how to write this code. EDIT: If there is an easier way to do it than with a for loop I am open to it. I was just told by my professor that its possible to use a nested for loop!
below is a sample of the data I am working with, any help would be much appreciated. thank you so much!
