createBubblechart: Create Bubble Chart type of plot.

Description

Create a bubble chart that utilizes three dimensions of data. It is a variation of the scatter plot with data points replaced with shapes ("bubbles"): x and y are bubble location and z is its size. It can optionally assign data points labels and fill shapes with colors.

Usage

createBubblechart(data, x, y, z, label = z, fill = NULL,
    facet = NULL, ncol = 1, facetScales = "fixed",
    xlim = NULL, baseSize = 12, baseFamily = "sans",
    shape = 21, shapeColour = "black", scaleSize = TRUE,
    shapeSizeRange = c(3, 10), shapeMaxSize = 100,
    paletteValues = NULL, palette = "Set1",
    title = paste("Bubble Chart by", fill), xlab = x,
    ylab = y, labelSize = 5, labelFamily = "",
    labelFontface = "plain", labelColour = "black",
    labelVJust = 0.5, labelHJust = 0.5, labelAlpha = 1,
    labelAngle = 0, legendPosition = "right",
    defaultTheme = theme_bw(base_size = baseSize, base_family = baseFamily),
    themeExtra = NULL)

Arguments

data

data frame contains data computed for bubblechart

name of a column containing x variable values

name of a column containing y variable values

name of a column containing bubble size value

label

name of a column containing bubble label

fill

name of a column with values to use for bubble colours

facet

vector of 1 or 2 column names to split up data to plot the subsets as facets. If single name then subset plots are placed next to each other, wrapping with ncol number of columns (uses face

ncol

number of facet columns (applies when single facet column supplied only - see parameter facet).

facetScales

Are scales shared across all subset plots (facets): "fixed" - all are the same, "free_x" - vary across rows (x axis), "free_y" - vary across columns (Y axis, default), "free" - both rows and columns (see in facet_wrap parameter

baseSize

theme base font size

baseFamily

theme base font family

xlim

a vector specifying the data range for the x scale and the default order of their display in the x axis.

shape

bubble shape

shapeColour

colour of shapes

scaleSize

logical if TRUE then scale the size of shape to be proportional to the value, if FALSE then scale the area.

shapeSizeRange

bubble size range (applies only when scaleSize = TRUE)

shapeMaxSize

size of largest shape (applies only when scaleSize = FALSE)

paletteValues

actual palette colours for use with scale_fill_manual (if specified then parameter palette is ignored)

palette

Brewer palette name - see display.brewer.all in RColorBrewer package for names

title

plot title.

xlab

a label for the x axis, defaults to a description of x.

ylab

a label for the y axis, defaults to a description of y.

labelSize

size of labels

labelFamily

label font name or family name

labelFontface

label font face (c("plain","bold","italic","bold.italic"))

labelColour

color of labels

labelVJust

position of the anchor (0=bottom edge, 1=top edge), can go below 0 or above 1

labelHJust

position of the label anchor (0=left edge, 1=right edge), can go below 0 or above 1

labelAlpha

the transparency of the text label

labelAngle

the angle at which to draw the text label

legendPosition

the position of legends. ("left", "right", "bottom", "top", or two-element numeric vector). "none" is no legend.

defaultTheme

plot theme to use: theme_bw (default), theme_grey, theme_classic or

themeExtra

any additional theme settings that override default theme.
