Hi all,
I have a very general question and I think for you maybe very easy, but I am not
able to solve it.
I have a dataset and that dataset contains the variable Anxiolytics. This
variable is coded as 0, 1, 2. The variable looks as follows:
> summary(DF$Anxiolytics)
0 1 2 NA's
1102 0 20 440
You can see that the variable is coded as 0, 1, 2, but group 1 is
'empty'. So I want to remove this group, such that I get:
> summary(DF$Anxiolytics)
0 2 NA's
1102 20 440
And then I want to recode the variable in a way that 2 becomes 1, such as:
> summary(DF$Anxiolytics)
0 1 NA's
1102 20 440
Can you help me with the code for doing this?
Thank you in advance!
Best, Lisa
