error code appearing in mutate function

Final_data<-TY2019_rides %>%
mutate(member_casual= Membership
,"Subscriber"= member
, "Customer" = casual )
error: Problem with mutate() column member_casual.

Can anyone explain why this code is not working in my Rstudio?? Am I entering something wrong?

Please provide a reproducible example:

FAQ: What's a reproducible example (reprex) and how do I create one?

If I had to totally guess, I assume that you don't have a column in your data called "Membership", but it is impossible to tell without seeing your data and code!

Further, one wouldn't use quotations within the left hand side of dplyr::mutate() - I'm not sure what the third and fourth lines of your code are trying to achieve.

member_casual = c("Subscriber",
"Subscriber", "Subscriber", "Subscriber", "Subscriber", "Subscriber",
"Subscriber", "Customer", "Customer", "Customer", "Customer",

the objective is for me to make change the name of the column and the variables in the rows. I was hoping to accomplish this by using the following function:

Final_data<-TY2019_rides %>%
mutate(member_casual= Membership
,"Subscriber"= member
, "Customer" = casual )

Thanks in advance for your replies

But what does TY2019_rides look like?

Anyway, I think you want something like case_when:

Is this what you're looking for?

yes. this is very helpful

additionally this is the reprex requested

Thanks again

all_trips <- all_trips %>% mutate(member_casual = recode(member_casual,
