triples.test1: North American Geochemical Soil Landscapes Project QA/QC data
Description
A small data set of QA/QC triplicates samples from the Maritimes 2007 NAmSGLs survey. The analyses are for source
The Geological Survey of Canada, see Open File 6433, from which this QA/QC subset for barium (Ba) was extracted.Details
The replicate status codes indicate the position of the geochemical sample in the QA/QC structure. RS = 8 indicates analytical duplicate, RS = 2 indicates the field duplicate, and RS = 1 indicates a routine regional coverage site that was duplicated. All other routine regional coverage sites are coded RS = 0. The analytical duplicate may be split from either of the two field sites, this information being in the project database. Thus the triples may ocur in the sequence 8, 2, 1 or 8, 1, 2. For gx.triples.aov to estimate the variance components correctly the geochemical samples must occur in the file in correct sequence.References
