### Examples

    require("dplyr")
    require("tidyr")

    ## Data set only goes through 1955
    ## Can get a more complete record from the Fielding data frame
    ## or from the Appearances data (see below)

    ## Output directly from the FieldingOF data

    ## Barry Bonds (no records: post-1955 player)
    FieldingOF %>%
       filter(playerID == "bondsba01")

    ## Willie Mays (first few years)
    FieldingOF %>%
      filter(playerID == "mayswi01")

    ## Ty Cobb (complete)
    FieldingOF %>%
      filter(playerID == "cobbty01")

    ## One way to get OF game information from the Fielding data
    ## Note: OF games != sum(LF, CF, RF) because players can switch
    ## OF positions within a game. Players can also switch from
    ## other positions to outfield during a game. OF represents
    ## the number of games a player started in the outfield.
    Fielding %>%
       select(playerID, yearID, stint, POS, G) %>%
       filter(POS %in% c("LF", "CF", "RF", "OF")) %>%
       tidyr::spread(POS, G, fill = 0) %>%
       filter(playerID == "trumbma01")

    ## Another way is through the Appearances data (no stint).
    ## Provides a somewhat nicer table than the above.

    ## Mark Trumbo (active player)
    Appearances %>%
       select(playerID, yearID, G_lf, G_cf, G_rf, G_of) %>%
       filter(playerID == "trumbma01")

    ## A slightly better format, perhaps
    Appearances %>%
      select(playerID, yearID, G_lf, G_cf, G_rf, G_of) %>%
      rename(LF = G_lf, CF = G_cf, RF = G_rf, OF = G_of) %>%
      filter(playerID == "trumbma01")

    ## Willie Mays (1951-1973)
    Appearances %>%
      select(playerID, yearID, G_lf, G_cf, G_rf, G_of) %>%
      filter(playerID == "mayswi01")

    ## Joe DiMaggio (1936-1951)
    Appearances %>%
      select(playerID, yearID, G_lf, G_cf, G_rf, G_of) %>%
      filter(playerID == "dimagjo01")
