Consider the following function:

get$\_$int$\_$repr function$(x,$ categories$)\{$

int$\_$repr integer$($length $(x))$

for $($index in seq along $(x))\{$

$\}$

int$\_$repr$[$index which$($x$[$index$]==$ categories$)$

$\}$

int$\_$repr

Write a command that will output the same result as get$\_$int$\_$repr$($x$,$ categories$),$

where $x$ and

are both character vectors that don't contain any missing values.
