Avoiding the infamous “eval(parse())” construct

Question

Ok, so I\'m running some loops to process data stored in list objects. Ever mindful of the infamous fortune admonishment not to use eval(parse(mystring))

Answer 1

Using get and [[:

bar <- list(foo = list(fast = 1:5, slow = 6:10),
            oof = list(6:10, 1:5))

rab <- 'bar'

get(rab)[['oof']]
# [[1]]
# [1]  6  7  8  9 10
# 
# [[2]]
# [1] 1 2 3 4 5
