In a text, you often you refer to a number (e.g. the number of observations in the estimation sample). There is a simple way to automise the export of this number from a Stata-do-file to a Latex-document. It works by generating another latex-document, which contains this number only. This newly created file can be included in the main latex-document. Here is how it works (example here: number of observations, where id is the identifier for individuals):

tab id

file open newfile using numberofobs.tex, write replace

file write newfile “`r(r)’”

file close newfile

This syntax generates the number of distinct values of variable id.
