scattersplot {npsp}

R Documentation

Exploratory scatter plots

Description

Draws (in a 2 by 2 layout) the following plots: a scatter plot with a color scale, the scatter plots of the response against the (first two) coordinates and the histogram of the response values.

Usage

scattersplot(x, ...)

## Default S3 method:
scattersplot(
  x,
  z,
  main,
  xlab,
  ylab,
  zlab,
  col = hot.colors(128),
  lowess = TRUE,
  density = FALSE,
  omd = c(0.05, 0.95, 0.01, 0.95),
  ...
)

## S3 method for class 'SpatialPointsDataFrame'
scattersplot(
  x,
  data.ind = 1,
  main,
  xlab,
  ylab,
  zlab,
  col = hot.colors(128),
  lowess = TRUE,
  density = FALSE,
  omd = c(0.05, 0.95, 0.01, 0.95),
  ...
)

Arguments

`x`	object used to select a method.
`...`	additional graphical parameters (to be passed to `spoints`).
`z`	vector of data (response variable).
`main`	an overall title for the plot.
`xlab`	a title for the axis corresponding to the first coordinate.
`ylab`	a title for the axis corresponding to the second coordinate.
`zlab`	a title for the axis corresponding to the response.
`col`	color table used to set up the color scale (see `spoints`).
`lowess`	logical. If `TRUE`, a `lowess` smooth is added to the plots of the response against the coordinates.
`density`	logical. If `TRUE`, a kernel `density` estimate is added to the histogram.
`omd`	a vector of the form `c(x1, x2, y1, y2)` giving the region inside outer margins in normalized device coordinates (i.e. fractions of the device region).
`data.ind`	integer (or character) with the index (or name) of the data component.

Details

Standard generic function with a default method, in which argument x is a matrix with the spatial coordinates (each row is a point).

scattersplot.SpatialPointsDataFrame sets default values for some of the arguments from attributes of the object x (if present; see e.g. precipitation).
