Subset a list (choose matching values for all components)

Question

I try to read out certain elements from a list in a way, thats equivalent to df[, c(1,4,5)] in a data.frame.

> obj <- list(c(1:5)         


        

Answer 1

EDi has a great answer, but you can do it by passing the [ function to lapply plus additional arguments:

lapply(obj, '[', c(1, 4, 5))

You can access this and the other "weird" functions in R by quoting them:
