- z
numeric
-- input matrix, array (2 dimensions) or data frame.
- xval
numeric
-- x-values and/or labels for the columns of z
.
if xval=TRUE
, the first row contains x-values for the columns.
- yval
numeric
-- y-values and/or labels for the rows of z
.
If yval=TRUE
, the first column contains y-values for the rows.
- dnam
logical
-- if TRUE
, attempt to use dimnames
of input
matrix z
as xval
and yval
. The dimnames
are
converted to numeric values and must be strictly increasing or decreasing.
If successful, these values will overwrite previously specified values
of xval
and yval
or any default indices.
- rpro
logical
-- if TRUE
, convert rows to proportions.
- cpro
logical
-- if TRUE
, convert columns to proportions.
- rres
logical
-- if TRUE
, use row residuals (subtract row means).
- cres
logical
-- if TRUE
, use column residuals (subtract column means).
- powr
numeric
-- power transform; radii are proportional to z^powr
.
Note: powr=0.5
yields bubble areas proportional to z
.
- size
numeric
-- size (inches) of the largest bubble.
- lwd
numeric
-- line width for drawing circles.
- clrs
character
-- colours (3-element vector) used for positive, negative,
and zero values, respectively.
- hide0
logical
-- if TRUE
, hide zero-value bubbles.
- frange
numeric
-- number specifying the fraction by which the range of the axes should be extended.
- prettyaxis
logical
-- if TRUE
, apply the pretty function to both axes.
- ...
dots
-- additional arguments for plotting functions.
