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)

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

Details

The smallest bubbles represent the 10% quantile and the biggest bubbles represent the 99

Value

Plots bubbles in the existing plot.
