r(101)

[Jeanne Pigou]

Hello!
I am using stata 13, I want to keep only variables that I need, so I just use "keep varlist", but stata shows that htere is an error r(101): factor variables and time-series operators are not allowed.
What shall I do?

Thank you

some of your variable names are clearly illegitimate (e.g., "FA3.3") as a dot is not allowed to be part of the variable name - therefore you need to explain more clearly what you are trying to do; it might help to include a sample of your data - if so, please download dataex and use it (ssc install dataex)

Yes, you are right. Thank you very much!
