Custom scatterplot matrix (SPLOM)

Description

A wrapper function around lattice 'splom' with different upper and lower panels. A scatterplot matrix is a tiled plot where all variables of a data frame are plotted against each other.

Usage

custom_splom(
  df,
  ...,
  aspect = 1,
  between = list(x = 0.5, y = 0.5),
  col_palette = c("steelblue", grey(0.95), "darkorange"),
  pscales = 4,
  strip = NULL,
  groups = NULL,
  main = NULL,
  xlab = NULL,
  ylab = NULL,
  pch = 19,
  col = grey(0.5),
  cex = 0.8
)

Arguments

df	(data.frame) data frame whose columns are plotted against each other
...	other arguments passed to the 'splom' function
aspect	(numeric) aspect ratio between height and width, default = 1.
between	(list) list with two named vectors x and y indicating space between panels
col_palette	(list) list of colors to use for colorRampPalette
pscales	(numeric) controls the number of ticks and tick labels to draw at axes
strip	(list) controlling strip appearance, defaults to NULL.
groups	(character) a grouping variable (untested feature)
main	(character) title of the plot
xlab	(character) label of X axis
ylab	(character) label of y axis
pch	(numeric) the plotting symbol to be used
col	(character) the color to be used
cex	(numeric) character size of the symbol

Examples

library(lattice)
data(mtcars)

# Draw a scatterplot matrix of all variables of a 
# data frame against each other.
custom_splom(mtcars[1:5])

# We can customize the scatterplot
custom_splom(
  mtcars[1:5],
  col_palette = rainbow(4),
  pscales = 10,
  xlab = "data points", ylab = "regression",
  pch = 1, col = 1, cex = 0.6
)
