Arguments

age	(integer) Age of players
pos	(character) Position of players, defaults to "all". To exclude pitchers, use "np".
stats	(character) Statistic to return. Defaults to "bat".
lg	(character) League to return. Defaults to "all". Options are "al", "nl", or "all".
qual	(character) Whether you want only batters/pitchers that qualified in a given season, or the minimum number of plate appearances for inclusion. If you only want qualified hitters, use qual. If a minimum number of plate appearaces/innings pitched, use the number desired. Defaults to "y".

When startdate/enddate are supplied and month is left at its default, it is set to "1000" automatically so the date filters take effect.

rost	(character) Whether or not to include players on the roster. 1 = include, 0 = exclude.
players	(character) Whether or not to include players on the roster. 1 = include only active roster players, 0 = exclude.
type	(character) Defaults to 8, which is the standard leaderboard. The values for the leaderboards appear to go to from type = 0 to 48+, which correspond to links on the leaderboard page.
postseason	(logical) Whether or not to include postseason data. TRUE = include postseason, FALSE = exclude postseason.
sortdir	(character) Sort direction. Options are "asc" or "desc" or "default".
