The minimum spanning network generated by this function is generated
via igraph's minimum.spanning.tree
. The resultant
graph produced can be plotted using igraph functions, or the entire object
can be plotted using the function plot_poppr_msn
, which will
give the user a scale bar and the option to layout your data.
The area of the nodes are representative of the number of samples. Because igraph scales nodes by radius, the node sizes in the graph are represented as the square root of the number of samples.
Each node on the graph represents a different multilocus genotype.
The edges on the graph represent genetic distances that connect the
multilocus genotypes. In genclone objects, it is possible to set the
multilocus genotypes to a custom definition. This creates a problem for
clone correction, however, as it is very possible to define custom lineages
that are not monophyletic. When clone correction is performed on these
definitions, information is lost from the graph. To circumvent this, The
clone correction will be done via the computed multilocus genotypes, either
"original" or "contracted". This is specified in the mlg.compute
argument, above.
If your incoming data set is of the class genclone
,
and it contains contracted multilocus genotypes, this function will retain
that information for creating the minimum spanning network. You can use the
arguments threshold
and clustering.algorithm
to change the
threshold or clustering algorithm used in the network. For example, if you
have a data set that has a threshold of 0.1 and you wish to have a minimum
spanning network without a threshold, you can simply add
threshold = 0.0
, and no clustering will happen.
The threshold
and clustering.algorithm
arguments can also be
used to filter uncontracted data sets.
graph 
a minimum spanning network with nodes corresponding to MLGs within the data set. Colors of the nodes represent population membership. Width and color of the edges represent distance. 
populations 
a vector of the population names corresponding to the vertex colors 
colors 
a vector of the hexadecimal representations of the colors used in the vertex colors 
Please see the documentation for
bruvo.dist
for details on the algorithm.
The edges of these graphs may cross each other if the graph becomes too large.
The nodes in the graph represent multilocus genotypes. The colors of the nodes are representative of population membership. It is not uncommon to see different populations containing the same multilocus genotype.
