In provenance: Statistical Toolbox for Sedimentary Provenance Analysis

Get a subset of provenance data

Description

Return a subset of provenance data according to some specified indices

Usage

## S3 method for class 'distributional'
subset(x, subset = NULL, select = NULL, ...)

## S3 method for class 'compositional'
subset(x, subset = NULL, components = NULL, select = NULL, ...)

## S3 method for class 'counts'
subset(x, subset = NULL, components = NULL, select = NULL, ...)

## S3 method for class 'varietal'
subset(x, subset = NULL, components = NULL, select = NULL, ...)

Arguments

x	an object of class distributional, compositional, counts or varietal.
subset	logical expression indicating elements or rows to keep: missing values are taken as false.
select	a vector of sample names
...	optional arguments for the generic subset function
components	vector of categories (column names) to keep

Value

an object of the same class as x

Examples

data(Namib)
coast <- c("N1","N2","T8","T13","N12","N13")
ZTRcoast <- subset(Namib$HM,select=coast,components=c('gt','cpx','ep'))
DZcoast <- subset(Namib$DZ,select=coast)
summaryplot(ZTRcoast,KDEs(DZcoast),ncol=2)
