egen nonmissing

[Jay Rege]

Hey,
I want to create a varibale which counts a number of countries.

egen Number_of_countries= rownonmiss (country1 country2 country3 country4 country5)

or egen Number_of_countries= count (country1 country2 country3 country4 country5)
The Variable Number_of_countries should Show the number of countries with nonmissingvalues or names, so a Maximum of 5

[Rich Goldstein]

what is the question? it appears that the code you show (if you deleted the space after "rownonmiss") should be exactly what you want

[Jay Rege]

Sorry for being unprecise

type mismatch
r(109);

The countries are all strings.
So the question is: What is wrong?
Or better, what do I have to Change you make it work

[Rich Goldstein]

if you look at the help file, you MUST use the "strok" option

[daniel klein]

The documentation for egen says

String variables may not be specified unless the strok option is also specified. If strok is specified, string variables will be counted as containing missing values when they contain "". Numeric variables will be counted as containing missing when their value is ">.".

So all you need is adding the strok option.

Do not get me wrong, but typing

help egen

is really the minimum that you are expected to do before posting on the list.

Best
Daniel

Thanks,
I must have overlooked the strok Option!
Sorry for that!
Thanks again!
