matrx
| Any numeric matrix or data.frame. |
collab
|
Optional character vector of column labels; the default is
dimnames(matrx)[[2]] . If no default exists, xgobi constructs its own
defaults.
|
rowlab
|
Optional character vector of row labels; the default is
dimnames(matrx)[[1]] . If no default exists, xgobi constructs its own
defaults.
|
colors
| Optional character vector, used to supply initial point colors to be used; the default is that all points are the same color. |
glyphs
| Optional integer vector, used to supply glyphs to be used on startup; the default is that all points are drawn with the same glyph. |
erase
| Optional integer vector of length equal to the number of rows in the data and composed of 1s and 0s. A 1 in position i specifies that point i should be erased. The default is a vector of 0s. |
lines
| Optional integer matrix, n by 2, which specifies by row number pairs of points to be connected by line segments. The default connecting line matrix connects each point to the one that follows it in the data; that is, (1 2), (2 3), (3 4), ...{}, (n-1, n). |
linecolors
| Optional integer vector, of length n where n is the number of lines specified by the 'lines' argument. It is used to supply line colors to be used on startup; the default is for all the lines to be drawn in the standard foreground color. |
resources
| Optional character vector created by clicking on the "Save Resources" button in XGobi (if this XGobi was initiated during an S session). |
title
|
Optional character string which defines the -title argument used by
X. The default is the name of the current matrix matrx. See documentation
for xgobi, or for X.
|
vgroups
| Optional integer vector, used to assign columns to groups for transformation and axis scaling. This vector must contain one integer for each variable. Columns to be grouped together should share the same integer. Default is the vector 1:(ncol(matrx)). |
std
|
Optional string; which standardization of view to use. Default is
"mmx" , minimum-maximum scaling, in which the view is centered at the
midpoint of the data, and all the data fits inside the plotting
window. Alternatives are "msd" , in which the plot is centered at the
mean of the data and dev standard deviations fit inside the plotting
region, or "mmd" in which the plot is centered at the median and dev
median absolute deviations are shown inside the plotting window.
|
dev
|
Optional numeric scalar; the number of standard deviations (if "msd"
is chosen) or median absolute deviations (if "mmd" is chosen) that will
be plotted inside the plotting window. Default is 2.
|
nlinkable
| Optional integer scalar, the number of rows to be used in linking of brushing and identification; the default is for all rows to be used. This feature can be used to link ordinary scatterplots with plots that have some decorations requiring additional points, such as clustering trees. |
subset
| Optional integer scalar, the number of rows to be included in the initial display. That is, all data will be read in, but an initial random sample will be drawn for display. Use the Subset panel on the Tools Menu to select a new subset during the session. |
display
|
Optional character string, identifying the monitor on which to display
the xgobi window. The default is "machine:0.0" where machine is the
name of the user's workstation. See documentation for xgobi or for X.
|
status
upon completion, i.e. 0
if ok.XGobi can be used to create vectors of brushing information and rotation coefficients; see the documentation for XGobi for details.
