bubbleFIN function

Bubbleplot due to Finnish method

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

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

Returns

Plots bubbles in the existing plot.
