Fast Implementation of a Key-Value Store

c(
    person("Winston", "Chang", email = "winston@rstudio.com", role = c("aut", "cre")),
    person(given = "RStudio", role = c("cph", "fnd")),
    person(given = "Tessil", role = "cph", comment = "hopscotch_map library")
    )

Fast implementation of a key-value store. Environments are commonly
    used as key-value stores, but every time a new key is used, it is added to
    R's global symbol table, causing a small amount of memory leakage. This can
    be problematic in cases where many different keys are used. Fastmap avoids
    this memory leak issue by implementing the map using data structures in C++.

Simple, Consistent Wrappers for Common String Operations

c(person(given = "Hadley",
             family = "Wickham",
             role = c("aut", "cre", "cph"),
             email = "hadley@rstudio.com"),
      person(given = "RStudio",
             role = c("cph", "fnd")))

A consistent, simple and easy to use set of
    wrappers around the fantastic 'stringi' package. All function and
    argument names (and positions) are consistent, all functions deal with
    "NA"'s and zero length vectors in the same way, and the output from
    one function is easy to feed into the input of another.
