R Documentation
Graph xy plot of variable (array) projections from ordination, between group analysis or coinertia analysis.
Description
Graph xy plot of variables using s.var, s.groups or s.match.col. Useful for visualising array
coordinates ($li) resulting from ord, bga or cia of microarray data.
a data.frame or matrix or object from ordbga or cia analysis with at least two
columns, containing x, y coordinates to be plotted
axis1
An integer, the column number for the x-axis. Default is 1,
so axes 1 is dudivar[,1]
axis2
An integer, the column number for the y-axis. Default is 2,
so axes 2 is dudivar[,2]
arraylabels
A vector of variables labels. Default is row.names(coord)
classvec
A factor or vector which describes the classes in
coord. Default is NULL. If included variables will be coloured by class.
graph
A character of type "groups", "simple", "labels", "groups2", "coinertia" or "coinertia2" which
specifies the type of plot type or "graph" to be drawn. By default the graph
will be selected depending on the class of cooord, and whether a classvector is specified
labelsize
Size of sample labels, by default=1
star
If drawing groups, whether to join samples to centroid creating a "star"
ellipse
If drawing groups, whether to draw an ellipse or ring around the samples
arraycol
Character with length equal to the number of levels in the factor classvec. Colors for each of the levels in the factor classvec
...
further arguments passed to or from other method
Details
plotarrays calls the function s.var, s.groups or s.match.col.
If you wish to return a table or list of the top array at
the end of an axis, use the function topgenes.
Value
An xy plot
Note
plotarrays plots variables using s.var, s.groups,
s.match.col which are modifieds version
of s.label, s.class. , and
s.match.
