Subset of C-horizon of Kola Data

This is a small rounded subset of the C-horizon data chorizon from package mvoutlier.

data(chorSub)

Format

A data frame with 61 observations on 10 variables. The variables contain scaled concentrations of chemical elements.

Details

This data set was produced from chorizon via these statements:

    data(chorizon, package = "mvoutlier")
    chorSub <- round(100*scale(chorizon[,101:110]))[190:250,]
    storage.mode(chorSub) <- "integer"
    colnames(chorSub) <- gsub("_.*", '', colnames(chorSub))
