Y |
(matrix) m by n relational matrix. |
U |
(matrix) m by 2 matrix of row factors of Y. |
V |
(matrix) n by 2 matrix of column factors of Y. |
row.names |
(character vector) names of the row objects. |
col.names |
(character vector) names of the columns objects. |
plotnames |
(logical) plot row and column names. |
vscale |
(scalar) scaling factor for V coordinates. |
pscale |
(scalar) scaling factor for plotting characters. |
lcol |
(scalar or vector) line color(s) for the nonzero elements of Y. |
rcol |
(scalar or vector) node color(s) for the rows. |
ccol |
(scalar or vector) node color(s) for the columns. |
pch |
(integer) plotting character. |
lty |
(integer) line type. |
jitter |
(scalar) a number to control jittering of nodes. |
bty |
(character) bounding box type. |
add |
(logical) add to existing plot |
This function creates a circle plot of a relational matrix or social network.
If not supplied via U
and V
, two-dimensional row factors and
column factors are computed from the SVD of Y
, scaled versions of
which are used to plot positions on the outside edge (U
) and inside
edge (V
) of the circle plot. The magnitudes of the plotting characters
are determined by the magnitudes of the rows of U
and V
.
Segments are drawn between each row object i
and column object
j
for which Y[i,j]!=0
.
