Read puzzle input as a data frame

Read in the puzzle input, or other file, as a data frame, one row per line. It assumes that the file is stored in the directory "./YYYY/day/DD", where YYYY and DD are the values of year and day. By default, the file name is "input". This file will exist in this location if the post was created using aoc_new_day(). class is tbl_df, the reading is done by readr::read_table(). If the class is data.frame, the reading is done by utils::read.table(). The defaults have been chosen to suit typical Advent of Code puzzle input.

Usage

  day,
  year = NULL,

  view = FALSE
