summaryAll {GCDkit}R Documentation

Statistics: Statistical summaries for the whole data set or its subset

Description

The function 'summaryAll' prints statistical summary for selected list of elements (majors as a default) and the current dataset (or its part). Functions 'summaryMajor' and 'summaryTrace' are entry points supplying the default lists for major- and trace elements.

Usage

summaryAll(elems = major, where = NULL, show.boxplot = FALSE, 
    show.hist = FALSE, silent=TRUE)
summaryMajor()
summaryTrace()

Arguments

elems

list of desired elements

where

list of desired samples to be processed

show.boxplot

logical, should be plotted the boxplots?

show.hist

logical, should be plotted the histograms?

silent

logical, should be the above chosen by the appropriate dialogues?

Details

The statistical summary involves number of observations, missing values, mean, standard deviation, minimum, 25% quartile, median (= 50% quartile), 75% quartile and maximum. The function also plots summary boxplots and histograms, if desired so.

The samples can be selected based on combination of three searching mechanisms (by sample name/label, range or a Boolean condition) - see selectSamples for details.

Even though as a default are assumed majors (SiO2, TiO2, Al2O3, FeOt, MnO, MgO, CaO, Na2O, K2O for 'summaryMajor') or selected trace (Rb, Sr, Ba, Cr, Ni, La, Eu, Y, Zr for 'summaryTrace') elements, the variable(s) to be displayed can be modified/specified in all cases. To this purpose serves the function 'selectColumnsLabels'.

In the specification of the variable can be used also arithmetic expressions, see calcCore for the correct syntax.
