tps.iso: Deformation isolines using Thin Plate Splines.

Description

tps.iso calculates deformations between two configurations and map them with or without isolines.

Usage

tps.iso(fr, to, amp=1, palette = col.summer,
        iso.nb = 500, iso.levels = 12, cont=TRUE, cont.col="black",
        shp = TRUE, shp.col =  rep(NA, 2), shp.border=col.gallus(2),
        shp.lwd = c(2, 2), shp.lty = c(1, 1))

Arguments

fr

The reference $(x; y)$ coordinates.

to

The target $(x; y)$ coordinates.

amp

An amplification factor of differences between fr and to.

palette

A color palette such those included in Momocs or produced with colorRampPalette.

iso.levels

numeric. The number of levels for mapping the deformations.

iso.nb

A numeric. The number of points to use for the calculation of deformation.

cont

logical. Whether to draw contour lines.

cont.col

A color for drawing the contour lines.

shp

logical. Whether to draw shapes.

shp.col

Two colors for filling the shapes.

shp.border

Two colors for drawing the borders.

shp.lwd

Two lwd for drawing shapes.

shp.lty

Two lty fro drawing the shapes.

Value

• No returned value.

Examples

data(bot)
botF <- eFourier(bot)
x <- meanShapes(botF, "type", nb.pts=80)
fr <- x$beer
to <- x$whisky
tps.iso(fr, to, iso.nb=2000, amp=3)
