\title{plot file location on a map}
\description{
plot the location of the file (longitude and latitude) on a map
}
\usage{
plotLatLongMap(lat, long, track=NULL, margin=0.1, col='red', 
		legend=NULL, pch=20, cex=1.5, lwd=1, zlab=NA, xlim=NULL, ylim=NULL, ...)
}
\arguments{
\item{lat}{vector of latitudes.}
\item{long}{vecor of longitudes.}
\item{track}{a dataframe of the cruise track (from the sds file) with longitude (long) and latitude (lat) named accordingly.}
\item{margin}{margin of longitude and latitude around edges of current position.}
\item{col}{vector of colors of the cruise track.}
\item{legend}{vector of named colors for use in a heatmap color legend.}
\item{pch}{point character}
\item{cex}{character expansion}
\item{lwd}{line width}
\item{zlab}{the label for the values of the heatmap color gradient passed as 'col'}
\item{xlim}{limit of x axis}
\item{ylim}{limit of y axis}
\item{...}{additional arguments to be passed to the plot function}
}
