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).

Examples

data(iris)
## Not run: 
pairsD3(iris[,1:4],group=iris[,5],
         labels=gsub(pattern = "\\.",replacement = " ", names(iris)))

## End(Not run)

Widget output function for use in Shiny

Description

Widget output function for use in Shiny

Usage

pairsD3Output(outputId, width = "100%", height = "400px")

Arguments

outputId

Shiny output ID

width

width default '100%'

height

height default '400px'

Widget render function for use in Shiny

Description

Widget render function for use in Shiny

Usage

renderPairsD3(expr, env = parent.frame(), quoted = FALSE)

Arguments

expr

pairsD3 expression

env

environment

quoted

logical, default = FALSE

Save a pairs plot to an HTML file

Description

Save a pairsD3 graph to an HTML file for sharing with others. The HTML can include it's dependencies in an adjacent directory or can bundle all dependencies into the HTML file (via base64 encoding).

Usage

savePairs(pairs, file, selfcontained = TRUE)

Arguments

pairs

plot to save (e.g. result of calling the function pairsD3).

file

File to save HTML into

selfcontained

Whether to save the HTML as a single self-contained file (with external resources base64 encoded) or a file with external resources placed in an adjacent directory.

Shiny interface to the pairsD3 function

Description

Opens a shiny GUI to facilitate interaction with the pairsD3 function

Usage

shinypairs(x, group = NULL, subset = NULL, labels = NULL)

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).

Examples

data(iris)
## Not run: 
shinypairs(iris)

## End(Not run)
