Calcium Content In Soil Samples.
Description
This data set contains the calcium content measured in soil samples taken from the 0-20cm layer at 178 locations within a certain study area divided in three sub-areas. The elevation at each location was also recorded.See geoR package for details.
Usage
data("dataca20")
Format
A data frame with 178 observations on the following 3 variables.
eastX Coordinate.
northY coordinate.
calcontCalcium content measured in mmol_c/dm^3.
altitudeA vector with the elevation of each sampling location,in meters.
areaA factor indicating the sub area to which the locations belongs.
