`MTgroup`	Vector, identifying the group membership of the midwater trawl tow locations to be mapped. The unique values of `MTgroup` should be a subset of `ACgroup`.
`ACgroup`	Vector, identifying the group membership of the acoustic transect locations to be mapped.
`sug`	Vector, identifying the unique groups to which locations may belong, default sort(unique(c(`MTgroup`, `ACgroup`))).
`MTID`	Vector, unique identification of each midwater trawl tow, same length as `MTgroup`.
`ACID`	Vector, identification of acoustic transects used to apportion each acoustic transect, same length as `ACgroup`.
`short`	Logical scalar, indicating aspect of map area. If TRUE, the default, the mapped area is assumed to be wider (longitudinally) than tall. Used to better arrange multiple maps on a single page.
`MTlon`	Numeric vector, longitudes of midwater trawl tow locations to map, in decimal degrees, same length as `MTgroup`.
`MTlat`	Numeric vector, latitudes of midwater trawl tow locations to map, in decimal degrees, same length as `MTgroup`.
`AClon`	Numeric vector, longitudes of acoustic transect locations to map, in decimal degrees, same length as `ACgroup`.
`AClat`	Numeric vector, latitudes of acoustic transect locations to map, in decimal degrees, same length as `ACgroup`.
`rlon`	A numeric vector of length 2, range of longitudes to map, in decimal degrees, default range(`MTlon`, `AClon`, na.rm=TRUE).
`rlat`	A numeric vector of length 2, range of latitudes to map, in decimal degrees, default range(`MTlat`, `AClat`, na.rm=TRUE).
`MTIDcol`	A scalar, the color used to map the midwater trawl locations, same length as `MTgroup`. If NULL, the default, a range of colors will be assigned automatically.
`mapcol`	A scalar, the color used to draw the map lines (e.g., lake boundary), default "gray".
`boxcol`	A scalar, the color used to draw the box around the map, default "gray".
`misscol`	A scalar, the color used to label maps with no locations in the given bygroup, default "brown".
`misstext`	A character scalar, the text used to label maps with no locations in the given bygroup, default " - No tows".
`mar`	A numeric vector of length 4, the number of lines of margin c(bottom, left, top, right) around each plotted map plot, default c(0, 0, 2.5, 0).
