 \usage{
-plotMesh(readMeshFileATLAS(<file name>)
+Plot a mesh:
+plotMesh(readMeshFileATLAS(<file name>))
+
+Plot the mesh for a list of material domains:
+plotMesh(readMeshFileATLAS(<file name>), <list-of-domains>)
+
+Plot the mesh for a list of material domains, specify if solid domains are shown:
+plotMesh(readMeshFileATLAS("data/pre_geom2D.atl"), <list-of-domains>, <showElem>)
+
+Plot the mesh for a list of material domains, specify if solid domains and edges are shown:
+plotMesh(readMeshFileATLAS("data/pre_geom2D.atl"), <list-of-domains>, <showElem>,<showEdges>)
 }
 \description{
 Mesh files are used in FEM solutions for PDE problems to describe the geometry of the problem and the materials.
 
 This package is used to parse a 2D mesh file in ATLAS format and plot the 2D mesh using a plot3D function. The function readMeshFileATLAS is loading a mesh data file in ATLAS format. Then use plotMesh to plot the data (elements and nodes) composing the mesh.
 }
 \examples{
-plotMesh(readMeshFileATLAS("data/pre_geom2D.atl")
+Plot a mesh:
+plotMesh(readMeshFileATLAS("data/pre_geom2D.atl"))
+
+Plot the mesh for a list of material domains (1,2 and 4):
+plotMesh(readMeshFileATLAS("data/pre_geom2D.atl"), c(1:2,4))
+
+Plot the mesh for a list of material domains (1,3), specify to show only material domains:
+plotMesh(readMeshFileATLAS("data/pre_geom2D.atl"), c(1,3), showElem=TRUE)
+
+Plot the mesh for a list of material domains (2,4), specify to show as wireframes:
+plotMesh(readMeshFileATLAS("data/pre_geom2D.atl"), c(2,4), showElem=FALSE, showEdges=FALSE)
