Pairs plot panel functions for diagonal cells: Diagonal Panel Functions for Table Pairs Plot

Description

Diagonal panel functions for pairs.table.

Usage

pairs_barplot(gp_bars = NULL,
  gp_vartext = gpar(fontsize = 17),
  gp_leveltext = gpar(),
  just_leveltext = c("center", "bottom"),
  just_vartext = c("center", "top"),
  rot = 0, abbreviate = FALSE, check_overlap = TRUE, fill = "grey",
  var_offset = unit(1, "npc"), ...)
pairs_text(dimnames = TRUE, gp_vartext = gpar(fontsize = 17), 
  gp_leveltext = gpar(), gp_border = gpar(), ...) 
pairs_diagonal_text(varnames = TRUE, gp_vartext = gpar(fontsize = 17, fontface = "bold"),
  gp_leveltext = gpar(), gp_border = gpar(), pos = c("right","top"),
  distribute = c("equal","margin"), rot = 0, ...)
pairs_diagonal_mosaic(split_vertical = TRUE, margins = unit(0, "lines"),
  offset_labels = -0.4, offset_varnames = 0,
  gp = NULL, fill = "grey", ...)

Arguments

dimnames

vector of logicals indicating whether the factor levels should be displayed (only used for pairs_text).

varnames

vector of logicals indicating whether the variable names should be displayed (only used for pairs_text_diagonal).

gp_bars

object of class "gpar" used for bars (only used for pairs_barplot). If unspecified, the default is to set the fill component of this object to the fill argument.

gp_vartext

object of class "gpar" used for the factor names.

gp_leveltext

object of class "gpar" used for the factor levels.

gp_border

object of class "gpar" used for the border (only used for pairs_text).

gp

object of class "gpar" used for the tiles (only used for pairs_diagonal_mosaic). If unspecified, the default is to set the fill component of this object to the fill argument.

fill

color vector or palette function used for the fill colors of bars (for pairs_barplot) or tiles (for pairs_diagonal_mosaic).

just_leveltext, just_vartext

character string indicating the justification for variable names and levels.

pos

character string of length 2 controlling the horizontal and vertical position of the variable names (only used for pairs_text_diagonal).

rot

rotation angle for the variable levels.

distribute

character string indicating whether levels should be distributed equally or according to the margins (only used for pairs_text_diagonal).

abbreviate

integer or logical indicating the number of characters the labels should be abbreviated to. TRUE means 1 character, FALSE causes no abbreviation.

check_overlap

If TRUE, some levels will suppressed to avoid overlapping, if any.

split_vertical

vector of logicals of length $k$, where $k$ is the number of margins of x (values are recycled as needed). A TRUE component indicates that the tile(s) of the corresponding dimension should be split vertically, F

margins

either an object of class "unit" of length 4, or a numeric vector of length 4. The elements are recycled as needed. The four components specify the top, right, bottom, and left margin of the plot, respectively. When a numeric

offset_labels, offset_varnames

numeric vector of length 4 indicating the offset of the labels (variable names) for each of the four sides of the plot.

var_offset

object of class "unit" specifying the offset of variable names from the bottom of the barplots created by pairs_barplot. If numeric, the unit defaults to "npc".

...

other parameters passed to the underlying graphics functions.

Value

• A function with one argument: the marginal table for the corresponding dimension.

Details

In the diagonal cells, the pairsplot visualizes statistics or information for each dimension (that is: the single factors) alone. pairs_text displays the factor's name, and optionally also the factor levels. pairs_barplot produces a barplot of the corresponding factor, along with the factor's name.

Examples

data("UCBAdmissions")

pairs(UCBAdmissions) # pairs_barplot is default
pairs(UCBAdmissions, diag_panel = pairs_text)

pairs(UCBAdmissions, diag_panel = pairs_diagonal_text)
pairs(Titanic, diag_panel = pairs_diagonal_text)
pairs(Titanic, diag_panel = pairs_diagonal_text(distribute = "margin"))
pairs(Titanic,
      diag_panel = pairs_diagonal_text(distribute = "margin", rot = 45))
