Produce a gsunflower scatter plot

Description

Multiple points are plotted as "sunflowers" with multiple leaves ("petals") such that overplotting is visualised instead of accidental and invisible.

Usage

gsunflowerplot(x, ...)

## Default S3 method:
gsunflowerplot(
  x,
  y = NULL,
  number,
  log = "",
  digits = 6L,
  xlab = NULL,
  ylab = NULL,
  xlim = NULL,
  ylim = NULL,
  add = FALSE,
  rotate = FALSE,
  pch = 16,
  cex = 0.8,
  cex.fact = 1.5,
  col = par("col"),
  bg = NA,
  size = 1/8,
  seg.col = 2,
  seg.lwd = 1.5,
  ...,
  grid = TRUE,
  col.grid = "grey90",
  col.acc = "white"
)

## S3 method for class 'formula'
gsunflowerplot(
  formula,
  data = NULL,
  xlab = NULL,
  ylab = NULL,
  ...,
  subset,
  na.action = NULL,
  grid = TRUE,
  col.grid = "grey90",
  col.acc = "white"
)

Arguments

`x`	numeric vector of `x`-coordinates of length `n`, say, or another valid plotting structure, as for `plot.default`, see also `xy.coords`.
`...`	further arguments to `plot` [if `add = FALSE`], or to be passed to or from another method.
`y`	numeric vector of `y`-coordinates of length `n`.
`number`	integer vector of length `n`. `number[i]` = number of replicates for `(x[i], y[i])`, may be 0. Default (`missing(number)`): compute the exact multiplicity of the points `x[], y[]`, via `xyTable()`.
`log`	character indicating log coordinate scale, see `plot.default`.
`digits`	when `number` is computed (i.e., not specified), `x` and `y` are rounded to `digits` significant digits before multiplicities are computed.
`xlab, ylab`	character label for x-, or y-axis, respectively.
`xlim, ylim`	`numeric(2)` limiting the extents of the x-, or y-axis.
`add`	logical; should the plot be added on a previous one ? Default is `FALSE`.
`rotate`	logical; if `TRUE`, randomly rotate the sunflowers (preventing artefacts).
`pch`	plotting character to be used for points (`number[i]==1`) and center of sunflowers.
`cex`	numeric; character size expansion of center points (s. `pch`).
`cex.fact`	numeric shrinking factor to be used for the center points when there are flower leaves, i.e., `cex / cex.fact` is used for these.
`col, bg`	colors for the plot symbols, passed to `plot.default`.
`size`	of sunflower leaves in inches, 1[in] := 2.54[cm]. Default: 1/8\", approximately 3.2mm.
`seg.col`	color to be used for the segments which make the sunflowers leaves, see `par(col=)`; `col = "gold"` reminds of real sunflowers.
`seg.lwd`	numeric; the line width for the leaves' segments.
`grid`	logical; if `TRUE`, a background grid will be drawn
`col.grid`	`grid` color
`col.acc`	`grid` accent color
`formula`	a `formula`, such as `y ~ x`.
`data`	a data.frame (or list) from which the variables in `formula` should be taken.
`subset`	an optional vector specifying a subset of observations to be used in the fitting process.
`na.action`	a function which indicates what should happen when the data contain `NA`s. The default is to ignore case with missing values.
