Element columns and constructs rows are ordered according to cluster criterion. Various distance measures as well as cluster methods are supported.

)A list of two hclust object, for elements and constructs
respectively.
repgrid object.
The distance measure to be used. This must be one of
"euclidean", "maximum", "manhattan",
"canberra", "binary", or "minkowski".
Default is "euclidean".
Any unambiguous substring can be given (e.g. "euc"
for "euclidean").
A vector of length two can be passed if a different distance measure for
constructs and elements is wanted (e.g.c("euclidean", "manhattan")).
This will apply euclidean distance to the constructs and
manhattan distance to the elements.
For additional information on the different types see
?dist.
The agglomeration method to be used. This should be (an
unambiguous abbreviation of) one of "ward",
"single", "complete", "average",
"mcquitty", "median" or "centroid".
Default is "ward".
A vector of length two can be passed if a different cluster method for
constructs and elements is wanted (e.g.c("ward", "euclidean")).
This will apply ward clustering to the constructs and
single linkage clustering to the elements. If only one of either
constructs or elements is to be clustered the value NA
can be supplied. E.g. to cluster elements only use c(NA, "ward").
The power of the Minkowski distance, in case "minkowski"
is used as argument for dmethod. p can be a vector
of length two if different powers are wanted for constructs and
elements respectively (e.g. c(2,1)).
Whether the constructs should be aligned before clustering
(default is TRUE). If not, the grid matrix is clustered
as is. See Details section in function cluster for more information.
The number of characters a construct is trimmed to (default is
10). If NA no trimming is done. Trimming
simply saves space when displaying the output.
Type of dendrogram. Either or "triangle" (default)
or "rectangle" form.
Numeric vector of normal device coordinates (ndc i.e. 0 to 1) to mark the widths of the regions for the left labels, for the bertin display, for the right labels and for the vertical dendrogram (i.e. for the constructs).
Numeric vector of normal device coordinates (ndc i.e. 0 to 1) to mark the heights of the regions for the horizontal dendrogram (i.e. for the elements), for the bertin display and for the element names.
Horizontal offset between construct labels and construct dendrogram and
(default is 0.01 in normal device coordinates).
Vertical offset between bertin display and element dendrogram and
(default is 0.01 in normal device coordinates).
cex for axis labels, default is .6.
Color for axis and axis labels, default is grey(.4).
Whether to draw axis showing the distance metric for the dendrograms
(default is TRUE).
additional parameters to be passed to function bertin.
