Error:unexpected error symbol in dxsumvars <- c("RID","Phase","VISCODE", "VISCODE2", "DXCHANGE"
I need to solve the error
Any help will be appreciated

Thanks a lot for your help I really appreciate.
I retried the code and did not have an error .

Output: I have "R data editor" as a spreadsheet. But I couldn't save it. How can I save it as an Excel file?

Thanks in advance
