R loops- why necessarily we have to convert any input data in to vector format?

While processing a column or many columns or a list for processing into any loop or apply group of functions, why is it necessary to convert it into vector? what's the rationale behind it.

You wouldn't necessarily. For example; columns typically are naturally vectors for example, and converting them to vector most often will give an identical result; a wasted operation.

(mydf <- data.frame(a=1:5))

Based on that its hard to know how to answer you.
