swath {gmGeostats}

Swath plots

Description

Plots of data vs. one spatial coordinate, with local average spline curve

Usage

swath(data, ...)

## Default S3 method:
swath(
  data,
  loc,
  pch = ".",
  withLoess = TRUE,
  commonScale = TRUE,
  xlab = deparse(substitute(loc)),
  ...,
  mfrow
)

## S3 method for class 'acomp'
swath(
  data,
  loc,
  pch = ".",
  withLoess = TRUE,
  commonScale = NA,
  xlab = deparse(substitute(loc)),
  ...
)

## S3 method for class 'ccomp'
swath(
  data,
  loc,
  pch = ".",
  withLoess = TRUE,
  commonScale = NA,
  xlab = deparse(substitute(loc)),
  ...
)

## S3 method for class 'rcomp'
swath(
  data,
  loc,
  pch = ".",
  withLoess = TRUE,
  commonScale = NA,
  xlab = deparse(substitute(loc)),
  ...
)

Arguments

data

data to be represented, compositional class, data.frame, or spatial data object (in which case, loc is a formula!)

...

further arguments to panel plots

loc

a numeric vector with the values for one coordinate

pch

symbol to be used for the individual points, defaults to "."

withLoess

either logical (should a loess line be added?) or a list of arguments to DescTools::lines.loess

commonScale

logical or NA: should all plots share the same vertical range? FALSE=no, TRUE=yes (default), for compositional data sets, the value NA (=all plots within a row) is also permitted and is actually the default

xlab

label for the common x axis (defaults to a deparsed version of loc)

mfrow

distribution of the several plots; it has a good internal default (not used for compositional classes)

Value

Nothing, as the function is primarily called to produce a plot

Methods (by class)

• default: swath plot default method

• acomp: Swath plots for acomp objects

• ccomp: Swath plots for ccomp objects

• rcomp: Swath plots for rcomp objects

Examples

data("Windarling")
library("sp")
compo = compositions::acomp(Windarling[,c("Fe","Al2O3","SiO2", "Mn", "P")])
Northing = Windarling$Northing
swath(compo, Northing)
wind.spdf = sp::SpatialPointsDataFrame(sp::SpatialPoints(Windarling[,6:7]), 
     data=compo)
swath(wind.spdf, loc=Northing)
