Hello,
I use the following command to generate a categorized bar graph:
graph bar (asis) q41a if grandom == 1, over(frandom_)
However, I receive the following message:
variables frandom_ _variables do not uniquely identify the observations
I don't understand why my "frandom_" variable need to identify the
observations uniquely.
(by the way I have an "id" variable which uniquely identifies observations)
I also do not understand what "_variables" refers to.
If I run the command without "asis" then I get the following:
graph bar q41a if grandom == 1, over(frandom_)
variable __000006 not found in using data
Anyone who might have an idea what's going on?
