I recommend to not communicate the for-loop as the go-to approach for working with lists. Instead it is recommend to use one of the many functions working on lists. To loop through and to find numbers or indices, this can look as follows:

numbers_list <- list(1, 2, 3, 4, 5)
squared_numbers <- lapply(numbers_list, FUN = function(x) x^2)
Position(squared_numbers,  f = function(x) x > 10)
Find(squared_numbers,  f = function(x) x > 10)

These base functions also are usually very fast.
