Example data as shipped with Carb by Mauz & Hoffmann (2014). In contrast to the original
data, NA values have been replaced by 0 and columns and rows have been transposed. Samples
are now organised in rows and parameters in columns.
The data can be used to test 'RCarb' and play with the secondary carbonatisation process.
Sample HD107 was renamed to LV107 for the sake of consistency with Fig. 4 in Mauz & Hoffmann (2014).
Example_Data: data.frame (28 x 29)
Each column has two attributes:
UNIT: the unit, so far applicable, e.g. "ppm"
DESCRIPTION: the column description
0.1.0
