tableplot: Tableplot: A Semi-graphic Display of a Table

Description

A tableplot (Kwan, 2008) is designed as a semi-graphic display in the form of a table with numeric values, but supplemented by symbols with size proportional to cell value(s), and with other visual attributes (shape, color fill, background fill, etc.) that can be used to encode other information essential to direct visual understanding. Three-way arrays, where the last dimension corresponds to levels of a factor for which the first two dimensions are to be compared are handled by superimposing symbols.

The specifications for each cell are given by the types argument, whose elements refer to the attributes specified in patterns.

Usage

tableplot(values, ...)
# S3 method for default
tableplot(
  values,
  types,
  patterns = list(list(0, "black", 1, "white", "white", 0, 0.5, "grey80", FALSE, 1)),
  title = "Tableplot",
  side.label = "row",
  top.label = "col",
  table.label = TRUE,
  label.size = 1,
  side.rot = 0,
  gap = 2,
  v.parts = 0,
  h.parts = 0,
  cor.matrix = FALSE,
  var.names = "var",
  ...
)

Value

None. Used for its graphic side effect

Arguments

values

A matrix or 3-dimensional array of values to be displayed in a tableplot

...

Arguments passed down to tableplot.default

types

Matrix of specification assignments, of the same size as the first two dimensions of values. Entries refer to the sub-lists of patterns. Defaults to a matrix of all 1s, matrix(1, dim(values)[1], dim(values[2])), indicating that all cells use the same pattern specification.

patterns

List of lists; each list is one specification for the arguments to cellgram.

title

Main title

side.label

a character vector providing labels for the rows of the tableplot

top.label

a character vector providing labels for the columns of the tableplot

table.label

Whether to print row/column labels

label.size

Character size for labels

side.rot

Degree of rotation (positive for counter-clockwise)

gap

Width of the gap in each partition, if partitions are requested by v.parts and/or h.parts

v.parts

An integer vector giving the number of columns in two or more partitions of the table. If provided, sum must equal number of columns.

h.parts

An integer vector giving the number of rows in two or more partitions of the table. If provided, sum must equal number of rows.

cor.matrix

Logical. TRUE for a correlation matrix

var.names

a list of variable names

Examples

data(cars)
cars.mod <- lm (mpg ~ cylinder + engine + horse + weight + accel + year,
                data=cars)
car::vif(cars.mod)

(cd <- colldiag(cars.mod, center=TRUE))
tableplot(cd, title = "Tableplot of cars data", cond.max = 30 )

data(baseball, package = "corrgram")

baseball$Years7 <- pmin(baseball$Years,7)

base.mod <- lm(logSal ~ Years7 + Atbatc + Hitsc + Homerc + Runsc + RBIc + Walksc,
               data=baseball)
car::vif(base.mod)

cd <- colldiag(base.mod, center=TRUE)
tableplot(cd)
