Unique values value?

[Esteban Jara]

How can I use in Stata the value obtained in "unique values" that the codebook command returns?
Thanks

Take a look at -help levelsof-. -levelsof- displays a sorted list of distinct values of varnames, which you can store in a local macro for future use with the local() option.

although -codebook- does not save this result, there are other commands that do, including -inspect- (saved as "r(N_unique)") or the user-written -distinct- (save as " r(ndistinct)"); use -search- to find and download -distinct-
