### Examples

    require("dplyr")

    ## World Series fielding record for Yogi Berra
    FieldingPost %>%
      filter(playerID == "berrayo01" & round == "WS")

    ## Yogi's career efficiency in throwing out base stealers
    ## in his WS appearances and CS as a percentage of his
    ## overall assists
    FieldingPost %>%
      filter(playerID == "berrayo01" & round == "WS" & POS == "C") %>%
      summarise(cs_pct = round(100 * sum(CS)/sum(SB + CS), 2),
                cs_assists = round(100 * sum(CS)/sum(A), 2))

    ## Innings per error for several selected shortstops in the WS
    FieldingPost %>%
      filter(playerID %in% c("belanma01", "jeterde01", "campabe01",
                             "conceda01", "bowala01"), round == "WS") %>%
      group_by(playerID) %>%
      summarise(G = sum(G),
                InnOuts = sum(InnOuts),
                Eper9 = round(27 * sum(E)/sum(InnOuts), 3))

    ## Top 10 center fielders in innings played in the WS
    FieldingPost %>%
      filter(POS == "CF" & round == "WS") %>%
      group_by(playerID) %>%
      summarise(inn_total = sum(InnOuts)) %>%
      arrange(desc(inn_total)) %>%
      head(., 10)

    ## Most total chances by position
    FieldingPost %>%
      filter(round == "WS" & !(POS %in% c("DH", "OF", "P"))) %>%
      group_by(POS, playerID) %>%
      summarise(TC = sum(PO + A + E)) %>%
      arrange(desc(TC)) %>%
      do(head(., 1))    # provides top player by position
