states,
levels,
col.fun=grey,
alaska='alaska'\%in\%tolower(states),
hawaii='hawaii'\%in\%tolower(states),
normalize=TRUE,
name=NULL,

}
\arguments{
\item{states}{List of the full names of the states.}
\item{levels}{The response variable to use to color code the states}
\item{col.fun}{A color function that takes the response variable and returns a color code.}
\item{alaska}{include an inset of alaska?}
\item{hawaii}{include an inset of Hawaii?}
\item{normalize}{Does the response variable need to be transformed to between 0 and 1. If False and levels is outside of [0,1] may cause errors depending on the col.fun.}
\item{name}{the name of the object.}
\item{vp}{Viewport for the object. used to embed within other objects.}
\item{gp}{grid graphics parameters, ie. a \link[grid]{gpar} object.}
\item{asp}{aspect ratio for the map.}
\item{...}{other parameters passed on.}
