How can I create a condition so that if a variable returns the value (empty) in r, it will convert to an actual 0, so I can include it in a larger data frame that will display the value '0' for that variable?
I do not know which variables will return empty, so I want to include this as a condition on all variables before I run the code.
Here is what I have:
groups_ba = df$unique_groups[groupdata_unique$`Appointment Type`=="BA GROUP"]
If the data contains the appointment type 'BA GROUP', I want the value of groups_ba to correspond to the number of BA GROUP, which it currently does. However, if the data does not contain the appointment type 'BA GROUP', I want the value of groups_ba to be 0, rather than what it currently gives me, which is 'empty'.
