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.
