Please let me know how to resolve the error “function ‘%+m%’ not found” when using the mutate function.
When you want to calculate dates considering month-end, you can use the “%m+%” operator to perform date addition (or subtraction) that takes month-end into account. By the way, the following error is caused by an incorrect notation of “%+m%”.
! could not find function "%+m%"
This can be resolved by correctly using “%m+%” instead.
