Plot of the factorial maps for the projection of a vector basis
Description
Usage
performs the scatter diagrams of the projection of a vector basis.
s.arrow(dfxy, xax = 1, yax = 2, label = row.names(dfxy),
clabel = 1, pch = 20, cpoint = 0, boxes = TRUE, edge = TRUE, origin = c(0,0),
xlim = NULL, ylim = NULL, grid = TRUE, addaxes = TRUE, cgrid = 1,
sub = "", csub = 1.25, possub = "bottomleft", pixmap = NULL,
contour = NULL, area = NULL, add.plot = FALSE)
Arguments
dfxy
xax
yax
label
clabel
pch
cpoint
boxes
edge
origin
xlim
ylim
grid
a data frame containing the two columns for the axes
the column number of x in dfxy
the column number of y in dfxy
a vector of strings of characters for the point labels
if not NULL, a character size for the labels used with par("cex")*clabel
if cpoint > 0, an integer specifying the symbol or the single character to be
used in plotting points
a character size for plotting the points, used with par("cex")*cpoint. If zero,
no points are drawn.
if TRUE, labels are framed
a logical value indicating whether the arrows should be plotted
the fixed point in the graph space, by default c(0,0) the origin of axes. The
arrows begin at cent.
the ranges to be encompassed by the x-axis, if NULL they are computed
the ranges to be encompassed by the y-axis, if NULL they are computed
a logical value indicating whether a grid in the background of the plot should be
drawn
