biplot(x, …)# S3 method for default
biplot(x, y, var.axes = TRUE, col, cex = rep(par("cex"), 2),

biplot
, a fitted object. For biplot.default
,
the first set of points (a two-column matrix), usually associated
with observations.TRUE
the second set of points have arrows
representing them as (unscaled) axes.palette
: if there it and the next colour as used,
otherwise the first two colours of the palette are used.x
, or
1:n
if the dimname is NULL
.y
, or
1:n
if the dimname is NULL
.var.axes
is true. The arrow head can be suppressed by
arrow.len = 0
.biplot.princomp
.
The function biplot.default
merely provides the
underlying code to plot two sets of variables on the same figure. Graphical parameters can also be given to biplot
: the size of
xlabs
and ylabs
is controlled by cex
.biplot.princomp
, also for examples.
