bubbleFIN: Bubbleplot due to Finnish method

Description

This function plots multivariate data with respect to the value. The size of the bubble represents the value of the datapoint.

Usage

bubbleFIN(x, y, z, radi = 10000, S = 9, s = 0.9, wa = 0, wb = 0.95, wc = 0.05,
plottitle = "BubblePlot", legendtitle = "Legend", text.cex = 1,
legtitle.cex = 1, backgr = "kola.background", leg = TRUE, ndigits = 1)

Value

Plots bubbles in the existing plot.

Arguments

x

x coordinates

y

y coordinates

z

measured value at point (x,y)

radi

scaling for the map

S, s

control the size of the largest and smallest bubbles

wa, wb, wc

factors which defines the shape of the exponential function

plottitle

the titel of the plot

legendtitle

the titel of the legend

text.cex

multiplier for the size of the labels

legtitle.cex

multiplier for the size of the legendtitle

backgr

which background should be used

leg

if TRUE the bubbles are plotted to the legend

ndigits

how much digits should be plotted at the legend
