R Single Vs Double Brackets at Gabriel Williamson blog

R Single Vs Double Brackets. The single and double square brackets are used as indexing operators in r programming language. [] = always returns object of same class (out of basic object classes), can select more than one element of an object. You can use double brackets to select elements in more or less the same way as single brackets. When you use single brackets, r selects individual train cars and returns them as a new train. Each car keeps its contents, but those contents are still inside a train car (i.e., a list). In short, a single bracket will always return you another list with number of elements equal to the number of elements or number of indices you pass into the single. In summary, the bracket operator [] is used to extract or subset elements from a list or dataframe, while preserving the original. The double square brackets in r can be used to reference data frame columns, as shown with the iris dataset.
