Description Usage Arguments Details Value Author(s) Examples

makeMEOWmap takes a dataset with values and a MEOW column and makes a map in ggplot2

makeMEOWmap(newdata, fillColName, regionColName = type, type = "ECOREGION",
  fillPal = brewer.pal(11, "Spectral"), pal = "Spectral",
  pathCol = "black", pathAlpha = 1, guide = guide_colourbar(title =
  fillColName), dataOut = FALSE, na.value = NA, add.worldmap = FALSE,
  fillAlphaColName = NULL, excludeNoDataAreas = T, prevggplot = NULL, ...)

`newdata`	dataset to be used
`fillColName`	name of the column with information to be used for a fill value
`regionColName`	data name of column with ecoregion, province, or realm names
`type`	are these values from an ECOREGION, PROVINCE, or REALM map. Defaults to "ECOREGION". Note all caps.
`fillPal`	The palatte used by `scale_fill_gradientn`. Defaults to `brewer.pal(11, "Spectral")`
`pal`	The palatte used by `scale_fill_manual` if data is categorical. Defaults to "spectral" from `RColorBrewer`
`pathCol`	The path color for regional outlines. Defaults to "black"
`pathAlpha`	The alpha of the regional outlines. Defaults to 1.
`guide`	What kind of guide should be used, and what should it's title be? Defaults to `guide_colourbar(title=fillColName)`
`dataOut`	Return a merged dataframe for plotting instead of a plot? Defaults to `FALSE`
`na.value`	How are NAs areas handled for fill? Defaults to making them not plot - NA.
`add.worldmap`	Should a map of the world be plotted under the regions? Defaults to FALSE
`fillAlphaColName`	Colname of column used to scale alpha level of fill
`excludeNoDataAreas`	Exclude areas/regions from the plot with no data?
`prevggplot`	A ggplot argument that this plot will be added on top of. If null, a new ggplot object is created.
`...`	Other arguments to be supplied to color scale
