plot_devsegments: Draws colored segments from a matrix of coordinates.

Description

Given a matrix of (x; y) coordinates, draws segments between every points defined by the row of the matrix and uses a color to display an information.

Usage

plot_devsegments(coo, cols, lwd = 1)

Arguments

coo

A matrix of coordinates.

cols

A vector of color of length = nrow(coo).

lwd

The lwd to use for drawing segments.

Examples

# NOT RUN {
# we load some data
guinness <- coo_sample(bot[9], 100)

# we calculate the diff between 48 harm and one with 6 harm.
out.6    <- efourier_i(efourier(guinness, nb.h=6), nb.pts=120)

# we calculate deviations, you can also try 'edm'
dev <- edm_nearest(out.6, guinness) / coo_centsize(out.6)

# we prepare the color scale
d.cut <- cut(dev, breaks=20, labels=FALSE, include.lowest=TRUE)
cols  <- paste0(col_summer(20)[d.cut], 'CC')

# we draw the results
coo_plot(guinness, main='Guiness fitted with 6 harm.', points=FALSE)
par(xpd=NA)
plot_devsegments(out.6, cols=cols, lwd=4)
coo_draw(out.6, lty=2, points=FALSE, col=NA)
par(xpd=FALSE)
