D3 scatterplot matrices — pairsD3 • pairsD3

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).

Examples

data(iris)
if (FALSE) {
pairsD3(iris[,1:4],group=iris[,5],
         labels=gsub(pattern = "\\.",replacement = " ", names(iris)))
}
