panel.parallel {lattice} | R Documentation |
This is the default panel function for parallel
.
panel.parallel(x, y, z, subscripts, groups = NULL, col, lwd, lty, alpha, common.scale = FALSE, lower, upper, ..., horizontal.axis = TRUE)
x, y |
dummy variables, ignored. |
z |
The data frame used for the plot. Each column will be coerced to numeric before being plotted, and an error will be issued if this fails. |
subscripts |
The indices of the rows of z that are to be displyed in this
panel.
|
groups |
An optional grouping variable. If specified, different groups are
distinguished by use of different graphical parameters (i.e., rows
of z in the same group share parameters).
|
col, lwd, lty, alpha |
graphical parameters (defaults to the settings for
superpose.line ). If groups is non-null, these
parameters used one for each group. Otherwise, they are recycled
and used to distinguish between rows of the data frame z .
|
common.scale |
logical, whether a common scale should be used columns of z .
Defaults to FALSE , in which case the horizontal range for
each column is different (as determined by lower and
upper ).
|
lower, upper |
numeric vectors replicated to be as long as the number of columns in
z . Determines the lower and upper bounds to be used for
scaling the corresponding columns of z after coercing them to
numeric. Defaults to the minimum and maximum of each column.
Alternatively, these could be functions (to be applied on each
column) that return a scalar.
|
... |
other arguments (ignored) |
horizontal.axis |
logical indicating whether the parallel axes should
be laid out horizontally (TRUE ) or vertically (FALSE ).
|
Produces parallel coordinate plots, which are easier to
understand from an example than through a verbal description. See
example for parallel
