guessTaskType {CodeDepends}

Guess the type of high-level task of a code block

This attempts to infer the type of the task being performed. There is a small set of known task types, listed in system.file("Vocabulary", package = "CodeDepends").

Currently this uses simple rules. In the future, we might use a classifier.

          d$abc = d$a + log(d$b)
          d[ d$foo == 1, ] = sample(n)
      })
