remove.overlap

along.lines

overwrite.lines

name of the group to which this layer belongs in view mode. Each group can be selected or deselected in the layer control item. Groups can either be specified as base or overlay groups in <code><a rd-options="" href="/link/tm_view?package=tmap&version=2.0" data-mini-rdoc="tmap::tm_view">tm_view</a></code> (arguments <code>base.groups</code> and <code>overlay.groups</code>).

This function is a wrapper of <code><a rd-options="" href="/link/tm_lines?package=tmap&version=2.0" data-mini-rdoc="tmap::tm_lines">tm_lines</a></code> and <code><a rd-options="" href="/link/tm_text?package=tmap&version=2.0" data-mini-rdoc="tmap::tm_text">tm_text</a></code> aimed to draw isopleths, which can be created with <code><a rd-options="tmaptools:smooth_map" href="/link/smooth_map?package=tmap&version=2.0&to=tmaptools%3Asmooth_map" data-mini-rdoc="tmaptools:smooth_map::smooth_map">smooth_map</a></code>.

Thematic maps are geographical maps in which spatial data distributions are visualized. This package offers a flexible, layer-based, and easy to use approach to create thematic maps, such as choropleths and bubble maps.
