Brilliant Blue tracer profile
Description
Digitised pictures of profiles that have been
excavated after Brilliant Blue tracer
experiments.
The picture were taken by the soil physics group at ETH Zurich, see
Source and References below.
Usage
path <- paste(system.file(package='SoPhy'), 'tracer', sep="/")
F04 <- read.picture(paste(path, "F04", sep="/"))
F04g <- read.picture(paste(path, "F04.G", sep="/"))
F06 <- read.picture(paste(path, "F06", sep="/"))
F06g <- read.picture(paste(path, "F06.G", sep="/"))
K06 <- read.picture(paste(path, "K06", sep="/"))
K06g <- read.picture(paste(path, "K06.G", sep="/"))
Format
3-dimensional array, where the last dimension codes red, green, blue,
and alpha.
