Comparison: subset and filter

A detailed introduction on subsetting is seen in Hadley Wickham’s Advanced R.

• The three subsetting operators.
• The six types of subsetting.
• Important differences in behaviour for different objects (e.g., vectors, lists, factors, matrices, and data frames).

Benjamin on Stack Overflow answered the question ¹ of the comparison between subset() and dplyr::filter().

• They are, indeed, producing the same result, and they are very similar in concept.

• As the data sets grow, filter seems gains the upper hand in efficiency.
