Title
Body
For example, how do I get a vector of each and every person's age in the list people below: > people = vector("list", 5) > people[[1]] = c(name="Paul", age=23) > people[[2]] = c(name="Peter", age=35) > people[[3]] = c(name="Sam", age=20) > people[[4]] = c(name="Lyle", age=31) > people[[5]] = c(name="Fred", age=26) > ages = ??? > ages [1] 23 35 20 31 26 Is there an equivalent of a Python list comprehension or something to the same effect?
