How does R decide on the mode of a vector?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'd started learning R recently and in one of the practice questions, this was asked




What will be the output of mode(c(12, 45, "30", 34*56))




Now, since the numeric data was in majority, I thought the answer would be numeric. But the given answer (which I'd later verified in R console) was character.



What is the reason behind this?

    numeric can always coerced to character.

    run debugonce(mode) and mode(c(12, 45, "30", 34*56)) again for playing with the internals, hence the why.

    @JohnCleaver so it's a useful tool to learn then! You basically enter a debug mode, where you can see the internal code of the function, can run and evaluate the code line by line and see how does the result change. Here, for example, you can try is.expression(x), is.call(x), etc, and understand which part will be executed by the mode function in the end. Finally, just type x and see how does your input look like, when passed to mode.

R has a hierarchy of returning the mode.



As given in the documentation for mode, (?mode to open its documentation)




"logical", "integer", "double", "complex", "raw", "character", "list", "expression", "name", "symbol" and "function"




gives the way how R returns the mode.



Here, if the vector has even one function, the mode is function. If there is no function present, R checks for symbol and so on.
