Description

Subsetting of logratioVariogram objects

Usage

## S3 method for class 'logratioVariogramAnisotropy'
x[i = NULL, j = NULL, ...]

Arguments

`x`	an object of class "logratioVariogram" or c("logratioVariogramAnisotropy", "logratioVariogram")
`i`	index or indexes of lags to be kept (if positive) or removed (if negative)
`j`	index or indexes of directions to be kept, only for objects of class c("logratioVariogramAnisotropy", "logratioVariogram")
`...`	extra arguments, ignored

Value

the selected variograms or lags, potentially of class "logratioVariogram" if only one direction is chosen

Examples

data("jura", package="gstat")
X = jura.pred[,1:2]
Zc = compositions::acomp(jura.pred[,7:9])
vg = logratioVariogram(data=Zc, loc=X)
vg[1]
vg = logratioVariogram(data=Zc, loc=X, azimuth=c(0,90))
vg[,1]
vg[1,1]
vg[1,]
