     US( xlim=c(-124.7, -67.1), ylim = c(25.2, 49.4), add=FALSE,shift=FALSE, ...)

_A_r_g_u_m_e_n_t_s:

    ylim: range of latitudes

     add: If true will add the world map to current plot  

   shift: If TRUE shifts to be centered on the Dateline and longitude
          runs from 0 to 360. If FALSE centers on Prime Meridian and
