Scatterplot Matrices

Description

A matrix of scatterplots is produced. Alternative version of pairs() (default S3 method) where all axes are on the bottom and left sides. Argument information copied from pairs(). NB! Better functionality for layout alterations is in the works.

Usage

pairs2(
  x,
  labels,
  panel = points,
  ...,
  horInd = 1:nc,
  verInd = 1:nc,
  lower.panel = panel,
  upper.panel = panel,
  diag.panel = NULL,
  text.panel = textPanel,
  label.pos = 0.5 + has.diag/3,
  line.main = 3,
  cex.labels = NULL,
  font.labels = 1,
  row1attop = TRUE,
  gap = 1,
  log = ""
)

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.
`labels`	the names of the variables.
`panel`	`function(x, y, ...)` which is used to plot the contents of each panel of the display.
`...`	arguments to be passed to or from methods. Also, graphical parameters (`par()`) can be given as can arguments to `plot` such as `main`. `par("oma")` will be set appropriately unless specified.
`horInd, verInd`	The (numerical) indices of the variables to be plotted on the horizontal and vertical axes respectively.
`lower.panel, upper.panel`	separate panel functions (or `NULL`) to be used below and above the diagonal respectively.
`diag.panel`	optional `function(x, ...)` to be applied on the diagonals.
`text.panel`	optional `function(x, y, labels, cex, font, ...)` to be applied on the diagonals.
`label.pos`	y position of labels in the text panel.
`line.main`	if `main` is specified, `line.main` gives the `line argument` to `mtext()` which draws the title. You may want to specify `oma` when changing `line.main`.
`cex.labels, font.labels`	graphics parameters for the text panel.
`row1attop`	logical. Should the layout be matrix-like with row 1 at the top, or graph-like with row 1 at the bottom? The latter (non default) leads to a basically symmetric scatterplot matrix.
`gap`	distance between subplots, in margin lines.
`log`	a character string indicating if logarithmic axes are to be used, see `plot.default()` or a numeric vector of indices specifying the indices of those variables where logarithmic axes should be used for both x and y. `log = "xy"` specifies logarithmic axes for all variables.
