I am trying to do an `innerjoin` on a TypedTable. This is shown in the TypedTable tutorial and manual, and it is suggested that `?innerjoin` will give the help for the function. On my Julia 1.10.4 I cannot find this function in Julia, nor TypedTables. TypedTables does not export this function.

When I do an internet search I can only find innerjoin in relation to DataFrames.jl. What am I missing?

> Data manipulation is possible throught the tools built into Julia (such as `map` , `filter` , and `reduce` ) and those provide by [SplitApplyCombine.jl](https://github.com/JuliaData/SplitApplyCombine.jl) (like `group` and `innerjoin` ).

You need to use SplitApplyCombine.jl to get those operations!
