D3 scatterplot matrices

Description

An interactive matrix of scatterplots is produced.

Usage

pairsD3(
  x,
  group = NULL,
  subset = NULL,
  labels = NULL,
  cex = 3,
  width = NULL,
  col = NULL,
  big = FALSE,
  theme = "colour",
  opacity = 0.9,
  tooltip = NULL,
  leftmar = 35,
  topmar = 2,
  diag = FALSE
)

Arguments

x

the coordinates of points given as numeric columns of a matrix or data frame. Logical and factor columns are converted to numeric in the same way that data.matrix does.

group

a optional vector specifying the group each observation belongs to. Used for tooltips and colouring the observations.

subset

an optional vector specifying a subset of observations to be used for plotting. Useful when you have a large number of observations, you can specify a random subset.

labels

the names of the variables (column names of x used by default).

cex

the magnification of the plotting symbol (default=3)

width

the width (and height) of the plot when viewed externally.

col

an optional (hex) colour for each of the levels in the group vector.

big

a logical parameter. Prevents inadvertent plotting of huge data sets. Default limit is 10 variables, to plot more than 10 set big=TRUE.

theme

a character parameter specifying whether the theme should be colour colour (default) or black and white bw.

opacity

numeric between 0 and 1. The opacity of the plotting symbols (default 0.9).

tooltip

an optional vector with the tool tip to be displayed when hovering over an observation. You can include basic html.

leftmar

space on the left margin

topmar

space on the bottom margin

diag

logical, whether or not the main diagonal is plotted (scatter plot of variables against themselves).
