How to create a dictionary / hash table by iterating through a column?

Question

I have a data frame of two columns: key and value and I would like to create a dictionary using the respective row of each column for each element of the dictionary / hash t

Answer 1

The easiest way is to change names after creating variables. So you can define a function like this:

cc <- function(name, value) {
    ret <- c(value)
    names(ret) <- name
    ret
}

cc(c(letters[1:2], "a name"), c(LETTERS[1:2], "a value"))

# output like this
#    a         b    a name 
#   "A"       "B" "a value"
