I am trying to learn DataFramesMeta LINQ similar syntax. I have not been able to come up the proper counter of following very simple DataFrames syntax for DataFramesMeta Get number of rows. combine(df, nrow)

There is no special case for this. There is no equivalent to Stata’s _N or dplyr’s n(). You can do @combine df $nrow But that kind of thing can’t be used inside transformations, so you can’t do @combine df :y = :x / $nrow I would only use @combine df $nrow if you really know what you are doin…
