Construct a Bubble Plot from a Matrix
Construct a bubble plot for a matrix z.
plotBubbles(z, xval=FALSE, yval=FALSE, dnam=FALSE, rpro=FALSE,
cpro=FALSE, rres=FALSE, cres=FALSE, powr=0.5, size=0.2, lwd=1,
clrs=c("black","red","blue"), hide0=FALSE, frange=0.1, prettyaxis=FALSE, ...)z |
input matrix, array (2 dimensions) or data frame. |
xval |
x-values and/or labels for the columns of |
yval |
y-values and/or labels for the rows of |
dnam |
logical: if |
rpro |
logical: if |
cpro |
logical: if |
rres |
logical: if |
cres |
logical: if |
powr |
power transform. Radii are proportional to |
size |
size (inches) of the largest bubble. |
lwd |
line width for drawing circles. |
clrs |
colours (3-element vector) used for positive, negative, and zero values, respectively. |
hide0 |
logical: if |
frange |
number specifying the fraction by which the range of the axes should be extended. |
prettyaxis |

additional arguments for plotting functions. |
The function plotBubbles essentially flips the z matrix
visually. The columns of z become the x-values while the rows of
z become the y-values, where the first row is displayed as the
bottom y-value and the last row is displayed as the top y-value. The
function's original intention was to display proportions-at-age vs. year.
