Parameter Descriptionx Object GADMWrapperdata data.frame - data to plotvalue String - the name of the column in the data.frame we want to plot (eg: an incidence in
epidemiology studies)breakssteps Integer - number of breaks. Default = 5. If breaks is NOT NULL this value is used
internally with cut().adm.join String - the name in GADM spdf dataset which will be joined with a column of the data.legend String - legend title. Default NULL.labels String vector labels for the legend. Default NULLpalette String - An RColorBrewer palette name or a String vector vector of colors. Default NULL.title String - Title of the plot. Default is an empty string.
