Graph pitches and the strike zone, with different ways to color code

sz_graph(batter = "all", pitcher = "all", count = "all",
  startdate = "2016-01-01", enddate = "2016-12-31", year = 0,
  stand = "R','L", throws = "R','L", size = 3, heatmap = FALSE,
  pitchtypes = "all", color.code = "pitchtype", plot.title = "default",
  save = FALSE, path = getwd())

`batter`	Defaults to "all". Input either a name or FanGraphs playerid.
`pitcher`	Defaults to "all". Input either a name or FanGraphs playerid.
`count`	Ball-strike count. Defaults to all. Input x instead of a number to get all counts; e.g. "3-x" for all 3-ball counts
`startdate`	Start date. Format yyyy-mm-dd. Defaults to 2016-01-01.
`enddate`	End date. Format yyyy-mm-dd. Defaults to 2017-01-01.
`year`	The year. Overrides startdate and enddate. Can only be one full year – use startdate and enddate for full control over date range.
`stand`	Batter handedness. Defaults to both.
`throws`	Pitcher handedness. Defaults to both.
`size`	Size of the points on the graph.
`heatmap`	Defaults to FALSE.
`pitchtypes`	Defaults to all. To include multiple pitch types, create an array: c("Four-seam fastball","Changeup","Breaking ball")
`color.code`	What the colors of the points signify. Defaults to "pitchtype". Other options: result, hittype, biptype. Must be in quotation marks.
`plot.title`	The title of the plot. Leave default unless you want a specific custom title.
`save`	Whether to save the graph. Defaults to FALSE.
`path`	Where to save the graph. Defaults to the current working directory.
